Abstract

A liquid crystal display device has a pair of substrates disposed in opposition to one another with a liquid crystal interposed therebetween, active elements formed on one of the pair of substrates, an organic film layer formed to cover the active elements, a light-shielding film formed on another of the pair of substrates, and a sealing material which sticks the pair of substrates together. In the liquid crystal display device, the sealing material is formed integrally along the entire periphery of a display screen, and one of the light-shielding layer and the organic film layer is formed to be extended beyond an area where the sealing material is formed, and the other of the light-shielding layer and organic film layer is formed inside the area where the sealing material is formed.

Claims (12)

1. A liquid crystal display device comprising:

a pair of substrates disposed in opposition to one another with a liquid crystal interposed therebetween;

active elements formed on one of the pair of substrates;

an organic film layer formed to cover the active elements;

a light-shielding film formed on another of the pair of substrates; and

a sealing material which sticks the pair of substrates together;

wherein the sealing material is integrally formed along the entire periphery of a screen;

wherein one of the light-shielding layer and the organic film layer is formed to be extended beyond an area where the sealing material is formed, and the other is formed inside the area where the sealing material is formed; and

wherein the sealing material has therein a spacer formed on one of the pair of substrates, and the organic film layer is formed to be opposed to the spacer and to be spaced apart from an organic film layer formed in another area.

2. A liquid crystal display device according to claim 1 , wherein the sealing material has photocuring properties.

3. A liquid crystal display device according to claim 1 , wherein the light-shielding layer is formed inside the area where the sealing material is formed.

4. A liquid crystal display device according to claim 1 , wherein the liquid crystal is formed by a drop method.
