Abstract
A color filter substrate includes a substrate and coloring layers having at least two different colors, wherein the adjacent edge portions of the coloring layers are overlapped with each other, and the height of the overlapped portion is higher than or equal to the height of the other portion of the coloring layers.
Claims25
A color filter substrate comprising a substrate, coloring layers having at least two different colors provided on said substrate and a smoothing layer covering said coloring layers, wherein the adjacent edge portions of said coloring layers are overlapped with each other, and the height of the overlapped portions is greater than or equal to the height of the other portions of said coloring layers,
- wherein the overlapped portions are shaded from light by a light-shading member formed on said substrate, the overlapped portions being positioned above said light-shading member, and
- wherein the whole surface of said smoothing layer, or a surface portion of said smoothing layer other than the surface corresponding to said overlapped portions, is flattened.
A liquid crystal display device comprising:
- a color filter substrate comprising:
- substrate;
- coloring layers of at least two different colors formed on said substrate, adjacent edge portions of said coloring layers overlapping each other and the height of the overlapped portions of said coloring layers being greater than or equal to the height of the other portions of said coloring layers;
- and
- a light-shading layer formed on said substrate and including light-shading portions arranged to shade the overlapped portions of said coloring layers from light;
- a counter substrate;
- and
- a liquid crystal layer disposed between said color filter substrate and said counter substrate,
- wherein the widths of the overlapped portions are 2 micrometers or more.
