Abstract
A liquid crystal panel includes a liquid crystal/polymer composite between two substrates, one of which having a matrix of pixel electrodes. A mosaic color filter of red, green and blue is provided above counterelectrodes or pixel electrodes. The average pore size of the resin component or of the diameter of liquid crystal droplets in the composite is selected according to the color of the color filter. The average of pore sizes is the largest for red, and the smallest for blue. The average of pore sizes of the resin on the switching elements and on the signal lines is smaller than that on the pixel electrodes. This liquid crystal display panel is used as a light bulb for a projection type television system. This liquid crystal display panel is also used as a viewfinder of a video camera.
