Abstract
To provide a liquid crystal display device having excellent display quality and a substrate to be used for such liquid crystal display device. A liquid crystal display device is provided with a pair of substrates; a liquid crystal sealed between the substrates, CF resin layers formed in a display area on the substrate; and a structure for sustaining a cell gap between the substrates in the display area. The structure is provided with a resin spacer layer occupying 90% or more of the volume of an organic member constituting the structure.
Claims5
A substrate for a liquid crystal display device comprising:
- a transparent substrate which sandwiches a liquid crystal in combination with an opposite substrate provided opposite thereto;
- a color separation filter which is formed on the transparent substrate;
- a resin spacer layer which is formed on the transparent substrate in order to maintain a cell gap in a display area between the opposite substrate and the transparent substrate, and of which an area overlapping other organic films is 50% or less of a total area of the resin spacer layer as viewed in a direction perpendicular to the substrate surfaces;
- and
- wherein an alignment film is the only organic film provided between the resin spacer layer and the substrate that supports TFTs of the liquid crystal display device.
