Abstract
Official abstract text for this publication.
In a liquid crystal display device, a light shielding film, a color filter, an overcoat film, and an alignment film are formed in this order on a counter substrate. However, the alignment film is not formed in a seal portion. When the alignment film is subjected to photo-alignment with ultraviolet radiation, a portion of the overcoat film not covered with the alignment film is degraded by ultraviolet radiation. In order to prevent moisture penetrating from the degraded overcoat film from reaching the light shielding film to thereby alter the light shielding film and from causing the peeling of the light shielding film, the color filter is disposed below the overcoat film to block the moisture.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid crystal display device comprising: a TFT substrate including a display region where pixels each including a TFT and a pixel electrode are formed in a matrix and where a counter electrode is formed; a counter substrate bonded to the TFT substrate with a sealing material in a seal portion at a periphery thereof and including a display region where a light shielding film and color filters of three colors are formed, an overcoat film is formed so as t…
