Abstract
A color filter is provided on the surface of a substrate that opposes liquid crystals. The color filter has a surface profile defining the state of alignment of the liquid crystals. More specifically, the color filter has a plurality of alignment control protrusions whose top portions extend in one direction. A thin alignment film is formed so as to cover the color filter having such a surface profile.
Claims16
A color filter substrate comprising:
- one of a pair of substrates for sandwiching liquid crystals;
- and
- color filters disposed on a surface of the one substrate that faces the liquid crystals, the color filters transmitting light of a particular wavelength and having surface profiles defining a state of alignment of the liquid crystals.
A liquid crystal display panel comprising:
- liquid crystals between a pair of opposing substrates;
- and
- color filters disposed on a surface of one of the pair of substrates that faces the liquid crystals, the color filters transmitting light of a particular wavelength and having surface profiles defining a state of alignment of the liquid crystals.
A method of producing a color filter substrate including one of a pair of substrates for sandwiching liquid crystals and color filters which transmit light of a particular wavelength, the method comprising:
- a first step of forming a resin layer on a surface of the one substrate that faces the liquid crystals;
- and
- a second step of selectively removing portions of the resin layer to form the color filters having surface profiles that define a direction of alignment of the liquid crystals.
