Abstract
Color filters are disposed over a substrate so as to transmit light of a wavelength corresponding to a specified color, and an inner surface of each color filter is a rough surface having ridges and valleys. Further, pigment particle groups in each of which a plurality of pigment particles are aggregated are dispersed in each color filter.

A color filter board comprising:
- a first substrate selected from a pair of substrates which oppose each other and between which a liquid crystal is sandwiched;
- and
- color filters disposed over said first substrate so as to transmit light of wavelengths corresponding to specified colors, each color filter including:
- an inner surface that is a rough surface having ridges and valleys;
- and
- dispersed particle groups each having a plurality of aggregated particles.
A liquid crystal display panel comprising:
- a pair of substrates which oppose each other, and between which a liquid crystal is sandwiched;
- and
- color filters disposed over one of said pair of substrates so as to transmit light of wavelengths corresponding to specified colors, each color filter including:
- an inner surface that is a rough surface having ridges and valleys;
- and
- dispersed particle groups each having a plurality of aggregated particles.
A method of manufacturing a color filter board having a first substrate selected from a pair of substrates between which a liquid crystal is sandwiched, and color filters which transmit light of specified wavelengths, the method comprising:
- the first step of forming the color filters over said first substrate by the use of a color filter forming composite which includes particle groups each having a plurality of aggregated particles;
- and
- the second step of shaping an inner surface of each of the color filters formed by said first step, into a rough surface which has ridges and valleys.
