Abstract

A liquid crystal display device includes: a TFT substrate that includes gate lines; and a driver circuit section that includes a gate driver that is connected to the gate lines. A frame region includes a wiring substrate that sandwiches the gate lines. The wiring substrate includes: a first wiring substrate that has first wiring lines that are connected to the gate lines; a second wiring substrate that has second wiring lines that are connected to the first wiring lines; and a third wiring substrate that is attached to the second wiring substrate and has third wiring lines that are connected to the second wiring lines and a gate driver.

Claims (35)

1. A display device, comprising:

a display device substrate that is a flexible plastic substrate having driver wiring lines formed thereon, a display region for displaying an image, and a frame region along a periphery of said display region; and

a driver circuit unit that is adjacent to said display region and said frame region and that has a driver circuit connected to said driver wiring lines;

wherein said driver wiring lines are drawn out from the display region to the frame region,

wherein the frame region has a wiring substrate on the display device substrate sandwiching the driver wiring lines that are drawn out on the frame region,

wherein said wiring substrate comprises:

a first wiring substrate that is provided on a side of the display device substrate facing the driver wiring lines and that has first wiring lines connected to the driver wiring lines drawn out on the frame region;

a second wiring substrate that is provided on a side opposite to the side of the display device substrate facing the driver wiring lines and that has second wiring lines connected to the first wiring lines; and

a third wiring substrate that is attached to the second wiring substrate and that has third wiring lines connected to the second wiring lines and the driver circuit,

wherein the first to third wiring substrates are other flexible plastic substrates, and

wherein the driver circuit is connected to the driver wiring lines via the first to third wiring lines.

2. The display device according to claim 1 , wherein the driver wiring lines are gate wiring lines.

3. The display device according to claim 1 , wherein the driver wiring lines are auxiliary capacitance lines.

4. The display device according to claim 1 , wherein the plastic substrate and the other plastic substrates are respectively formed of at least one of a polyimide resin and an acrylic resin.

5. The display device according to claim 1 , further comprising:
