Abstract

A liquid crystal display device includes a liquid crystal panel including a first translucent substrate and a second translucent substrate between which a liquid crystal material is sealed; a flexible wiring board extending from a connection end portion with respect to the first translucent substrate; and a metal-reinforced resin container. The container includes a first principal surface onto which the liquid crystal panel is accommodated; a second principal surface onto which a printed wiring board is disposed; and a through hole for allowing an extended end portion of the flexible wiring board to pass therethrough from the first principal surface to the second principal surface so that the extended end portion is connected to the printed wiring board. The through hole is provided at a position corresponding to an overlapping portion between the first translucent substrate and the second translucent substrate.

Claims (29)

1. A liquid crystal display device, comprising:

a liquid crystal panel including a first translucent substrate and a second translucent substrate between which a liquid crystal material is sealed, the first translucent substrate including a drive circuit thereon and being larger in dimensions than the second translucent substrate;

a flexible wiring board onto which a component is mounted, the flexible wiring board extending from a connection end portion with respect to the first translucent substrate of the liquid crystal panel; and

a metal-reinforced resin container including:

a first principal surface onto which the liquid crystal panel is accommodated;

a second principal surface onto which a printed wiring board is disposed; and

a through hole for allowing an extended end portion of the flexible wiring board to pass therethrough from the first principal surface to the second principal surface so that the extended end portion is connected to the printed wiring board, the through hole being provided at a position corresponding to an overlapping portion between the first translucent substrate and the second translucent substrate.

2. The liquid crystal display device according to claim 1 , wherein the metal-reinforced resin container including the through hole includes a metal plate including a through hole at the same position as a position of the through hole included in the metal-reinforced resin container, the metal plate being integrally molded with the metal-reinforced resin container.

3. The liquid crystal display device according to claim 2 , wherein the metal plate includes one of a continuous erect wall and a part-coupling erect wall at four edge portions.

4. The liquid crystal display device according to claim 1 , wherein the through hole of the metal-reinforced resin container is provided to have minimum dimensions necessary for allowing the extended end portion of the flexible wiring board to pass therethrough from the first principal surface to the second principal surface.

5. The liquid crystal display device according to claim 1 , wherein the metal-reinforced resin container further includes a concave portion in the first principal surface, in which the component mounted on the flexible wiring board is disposed.

6. The liquid crystal display device according to claim 5 , wherein the metal-reinforced resin container further includes a member in the concave portion, which eliminates an arrangement gap of the component.

7. The liquid crystal display device according to claim 1 , wherein, when a metal plate including a through hole at the same position as a position of the through hole included in the metal-reinforced resin container is integrally molded with the metal-reinforced resin container, the metal-reinforced resin container forms, in cooperation with the metal plate, a concave portion in the first principal surface, in which the component mounted on the flexible wiring board is disposed.

8. The liquid crystal display device according to claim 7 , wherein the metal-reinforced resin container further includes a member in the concave portion, which eliminates an arrangement gap of the component.

9. An electronic device, comprising:

a liquid crystal display device, including:

a liquid crystal panel including a first translucent substrate and a second translucent substrate between which a liquid crystal material is sealed, the first translucent substrate including a drive circuit thereon and being larger in dimensions than the second translucent substrate;

a flexible wiring board onto which a component is mounted, the flexible wiring board extending from a connection end portion with respect to the first translucent substrate of the liquid crystal panel; and

a metal-reinforced resin container including:

a first principal surface onto which the liquid crystal panel is accommodated;

a second principal surface onto which a printed wiring board is disposed; and

a through hole for allowing an extended end portion of the flexible wiring board to pass therethrough from the first principal surface to the second principal surface so that the extended end portion is connected to the printed wiring board, the through hole being provided at a position corresponding to an overlapping portion between the first translucent substrate and the second translucent substrate.

10. The electronic device according to claim 9 , wherein the metal-reinforced resin container including the through hole includes a metal plate including a through hole at the same position as a position of the through hole included in the metal-reinforced resin container, the metal plate being integrally molded with the metal-reinforced resin container.

11. The electronic device according to claim 10 , wherein the metal plate includes one of a continuous erect wall and a part-coupling erect wall at four edge portions.

12. The electronic device according to claim 9 , wherein the through hole of the metal-reinforced resin container is provided to have minimum dimensions necessary for allowing the extended end portion of the flexible wiring board to pass therethrough from the first principal surface to the second principal surface.

13. The electronic device according to claim 9 , wherein the metal-reinforced resin container further includes a concave portion in the first principal surface, in which the component mounted on the flexible wiring board is disposed.

14. The electronic device according to claim 13 , wherein the metal-reinforced resin container further includes a member in the concave portion, which eliminates an arrangement gap of the component.

15. The electronic device according to claim 9 , wherein, when a metal plate including a through hole at the same position as a position of the through hole included in the metal-reinforced resin container is integrally molded with the metal-reinforced resin container, the metal-reinforced resin container forms, in cooperation with the metal plate, a concave portion in the first principal surface, in which the component mounted on the flexible wiring board is disposed.

16. The electronic device according to claim 15 , wherein the metal-reinforced resin container further includes a member in the concave portion, which eliminates an arrangement gap of the component.
