Abstract

To reduce misalignment between pixels and color filters caused by thermal expansion of substrates in a liquid crystal display device in which an opposing substrate including a resin and including color filters is disposed over a TFT substrate including a glass substrate. Glass fibers are included extendedly in the direction of a black arrow in the opposing substrate. Consequently, the thermal expansion coefficient of the opposing substrate in the direction of the black arrow is close to the thermal expansion coefficient of glass fibers and hence the difference in thermal expansion in the direction of the black arrow between the TFT substrate and the opposing substrate is small. Meanwhile, although the thermal expansion of the opposing substrate in the direction perpendicular to the black arrow is large, color purity is not influenced even if misalignment occurs in the direction.
