Liquid crystal display panel

DETAILED DESCRIPTION This invention was accomplished to overcome these problems.
The object of the invention is to enable even a liquid crystal display panel having a color filter and/or a reflecting film on its pixel regions to achieve enhanced light transmittance and a bright display and also enable it to effect display with good efficiency by use of an auxiliary light source under condition of insufficient external light.
Another object of the invention is to enable a liquid crystal layer filled between two substrates to be efficiently exposed with ultraviolet light so that a polymer can be readily subjected to a crosslinking reaction for obtaining a polymer with a crosslinked structure in the case of using a liquid crystal layer composed of a polymer dispersive liquid crystal that is a mixture of liquid crystal and a polymer.
This invention achieves this object by providing a liquid crystal display panel having a first substrate and a second substrate composed of a transparent material and disposed opposite each other across a gap, multiple display electrodes provided on one of the opposed surfaces of the first and second substrates, multiple transparent counter electrodes provided on the other opposed surface, a region between each display electrode and an opposed counter electrode constituting a pixel region, and a liquid crystal layer filled in the gap between the first substrate and the second substrate, the liquid crystal display panel comprising a color filter or a reflecting film provided at each pixel region, the area of the color filter or the reflecting film at each pixel region being made smaller than the area of a single pixel region to leave a light transmitting portion around each color filter or reflecting film.
The color filter or the reflecting film at each pixel region is preferably divided into multiple segments.
The color filters or reflecting films provided at the pixel regions can have portions whose light transmittance is higher than other portions thereof.
In this case, the portions whose light transmittance is high are preferably multiple openings in the color filters or the reflecting films
