Abstract

A display device includes: a display panel including a first curved portion that is curved; and a drive circuit board on which a circuit for driving the display panel is formed. The drive circuit board includes a second curved portion that is curved following the first curved portion, and each of a plurality of components including one of a resistor and a capacitor and mounted on the second curved portion is mounted on the drive circuit board so that a crosswise direction of the component in plan view, which is a direction perpendicular to an alignment direction of a plurality of electrodes of the component, follows a curving direction of the second curved portion.

Claims (34)

1. A display device comprising:

a display panel including a first curved portion curved in a direction of a curvature; and

a plurality of drive circuit boards, each of the drive boards having a circuit configured to drive the display panel,

wherein each of the plurality of the drive circuit boards

includes a second curved portion that follows the curvature of the first curved portion, and

includes a plurality of components disposed thereon, the plurality of the components arranged in the direction of the curvature,

wherein each of the components includes a first electrode, a second electrode, and a chip,

wherein the first electrode, the second electrode and the chip are aligned in a direction perpendicular to the direction of the curvature,

wherein the chip is disposed between the first electrode and the second electrode,

wherein the plurality of the drive circuit boards are arranged on four sides of the display panel,

wherein each of the plurality of the drive circuit boards includes multiples of the chip arranged in a row direction in an array, and

wherein the multiples of the chip arranged in the row direction in the array matches a curvature of the first curved portion of the display panel.

2. The display device according to claim 1 ,

wherein, for each of the plurality of drive circuit boards, the plurality of components is mounted on a surface of a respective drive circuit board so that an alignment direction of a plurality of connection portions to which each of the components is soldered follows the direction perpendicular to the direction of the curvature.

3. The display device according to claim 1 ,

wherein each of the drive circuit boards is disposed on a side of the display panel that is opposite a display screen side of the display panel, so that the second curved portion of each of the drive circuit boards overlaps the first curved portion at a position corresponding to the first curved portion.

4. The display device according to claim 1 ,

wherein, for each of the plurality of drive circuit boards, the plurality of components is included in the circuit.

5. The display device according to claim 1 ,

wherein, for each of the plurality of drive circuit boards, in each drive board including the chip, one end of the first electrode contacts a first end of the chip, and one end of the second electrode contacts a second end of the chip.

6. The display device according to claim 1 ,

wherein each of the plurality of components is a surface mount device (SMD).

7. The display device according to claim 1 ,

wherein the plurality of the drive circuit boards are arranged at a perimeter of the display panel.

8. The display device according to claim 1 ,

wherein the plurality of the drive circuit boards includes

a first set of drive circuit boards arranged along the direction of the curvature, and

a second set of drive circuit boards arranged along the direction perpendicular to the direction of the curvature.

9. The display device according to claim 1 ,

wherein each of the plurality of the drive circuit boards is a rectangular board.

10. The display device according to claim 1 ,

wherein each of the plurality of the drive circuit boards disposed in the row direction of the display panel is bent to match a curvature of the first curved portion of the display panel.

11. The display device according to claim 1 ,

wherein two of the plurality of the drive circuit boards are disposed to meet at a corner of the display panel.
