Claims15
A liquid crystal display device comprising:
- a substrate;
- a plurality of gate lines and a plurality of data lines provided to cross each other on the substrate;
- a plurality of pixel regions divided by the gate lines and the data lines;
- a color filter layer provided on each of the pixel regions;
- a pixel electrode and a common electrode corresponding thereto provided on the same plane of each of the color filter layers;
- a liquid crystal orientation layer provided on the color filter layer, the pixel electrode and the common electrode;
- and
- a light reflection reducing layer provided each of between the liquid crystal orientation layer and the pixel electrode and between the liquid crystal orientation layer and the common electrode,
- wherein one surface of the light reflection reducing layer adjoins the pixel electrode or the common electrode, the other surface of the light reflection reducing layer adjoins the liquid crystal orientation layer, and
