ABSTRACT:
A photomask (5) of a liquid crystal display panel is formed by photolithographic exposure of a photosensitive resin layer through micro-lenses (3), and the apertures thereof are in complete alignment with condensed light through the micro-lenses, so that unnecessary light, such as strayed light, can be effectively masked. The liquid crystal display panel thus formed is provided with an increased effective aperture rate and suitable for a clearer image display.
