ABSTRACT:
A color filter composition, a color display device, and a production method of the same with which an increase of the luminance, an increase of the contrast, an increase in the range of color reproduction, and an improvement of the function for preventing reflection of outside light can be achieved. The color filter composition has a spectral characteristic allowing specific light of the visible region to pass therethrough and is composed of fine particles of an inorganic metal oxide containing 15 percent by weight or less of particles having a particle size of 0.1 .mu.m or more based on the weight of all of the particles and contains 70 percent by weight or more of particles having a particle size of 0.01 .mu.m to 0.07 .mu.m based on the weight of all of the particles. A color filter is formed on an inner surface of a panel of a display device by screen printing or heat transfer printing by using this color filter composition.
