Abstract

Claims (13)

1. A liquid crystal display device comprising: a first substrate; a second substrate which sandwiches a liquid crystal between itself and the first substrate; and a seal agent which, as well as bonding the first substrate and the second substrate together, seals the liquid crystal, wherein

the first substrate has thin film transistors and a wiring connection portion in which are formed terminals connected to the thin film transistors,

a wiring substrate connected to the terminals is disposed in the wiring connection portion,

the second substrate is a plastic substrate, and has an adhesive layer and an inorganic insulating layer formed on top of the adhesive layer, and

the adhesive layer covers the wiring connection portion and one portion of the wiring substrate.

2. The liquid crystal display device according to claim 1 , wherein the second substrate has a color filter layer on top of the inorganic insulating layer.

3. The liquid crystal display device according to claim 1 , wherein the wiring substrate is a flexible printed substrate.

4. The liquid crystal display device according to claim 1 , wherein the inorganic insulating layer is a silicon nitride layer.

5. The liquid crystal display device according to claim 1 , wherein

the first substrate is a plastic substrate, and has an adhesive layer and an inorganic insulating layer formed on top of the adhesive layer, and

the thin film transistors and the wiring connection portion are formed on the inorganic insulating layer on the first substrate.

6. The liquid crystal display device according to claim 1 , wherein the first substrate is a glass substrate.

7. The liquid crystal display device according to claim 1 , wherein a material of the seal agent and a material of the adhesive layer are different.
