Abstract

The instant application describes a liquid crystal display device comprising: a liquid crystal display; a circuit board including a top surface, a bottom surface, and a drive circuit for driving the liquid crystal display; and a flexible circuit board for connecting the liquid crystal display and the circuit board to each other. The flexible circuit board includes a first end connected to the liquid crystal display and a second end connected to the bottom surface of the circuit board. The flexible circuit board is configured to wrap around the circuit board, covering the top surface and the bottom surface of the circuit board. The top surface of the circuit board is fixed to the flexible circuit board.

Claims (15)

1. A liquid crystal display device comprising:

a liquid crystal display;

a circuit board including a drive circuit for driving the liquid crystal display;

a flexible circuit board for connecting the liquid crystal display and the circuit board to each other; and

a touch panel provided to cover a display surface of the liquid crystal display, wherein:

the flexible circuit board has a first end connected to the liquid crystal display and a second end connected to the circuit board,

the touch panel has a protruding portion protruding from the liquid crystal display in plan view,

the circuit board is fixed to a bottom surface of the protruding portion of the touch panel, and

the flexible circuit board includes:

a first portion extending from the first end along a bottom surface of the touch panel,

a second portion extending from the first portion and being folded away from the bottom surface of the touch panel, and

a third portion extending from the second portion toward the second end along a bottom surface of the circuit board.

2. The liquid crystal display device according to claim 1 , wherein the circuit board is fixed to a bottom surface of the touch panel by an adhesive tape.

3. The liquid crystal display device according to claim 1 , wherein a plurality of flexible circuit boards, each of which is the flexible circuit board, are arranged so as to be apart from each other.

4. The liquid crystal display device according to claim 1 , wherein the bottom surface of the protruding portion of the touch panel is opposed to the liquid crystal display.
