Patent ID: 8908128

Claim:
A color filter substrate comprising: a black matrix pattern of a light shielding layer formed on a transparent substrate, said black matrix pattern including a first pattern located on a display area and a second pattern located on a periphery of said display area so as to form a frame pattern of said black matrix pattern; three color layer patterns of resin material formed on said transparent substrate, the three color layer patterns being of red, green, and blue respectively; a planarization pattern layer formed on said substrate so as to cover at least an outer step portion of said frame pattern; wherein said planarization pattern layer is one of i) a single layer made of a resin material including a pigment for forming said color layer pattern of each color or ii) a transparent resin material layer for displaying white, wherein said color layer patterns are arranged with a stripe formed against said black matrix pattern, and said color layer patterns are also arranged with a stripe formed on said frame pattern including outside of said display area as a dummy pixel, and wherein i) two of the three said color layer patterns on said frame pattern and said planarization pattern layer, or ii) one of the three said color layer patterns and said planarization pattern layer, are connected on said frame pattern to form connected patterns with a connected color layer pattern and a connected planarization pattern layer such that a cross section of a portion of the connected patterns has a structure where i) a first one of an edge of said connected color layer pattern and an edge of said connected planarization pattern layer has a forward tapered shape and ii) a second one of the edge of said connected color layer pattern and the edge of said connected planarization pattern layer has an inverse tapered shape, and said portions of said connected patterns are arranged parallel on said frame pattern along said planarization pattern layer.
