摘要： A soluble polyimide solution is applied to the color filter substrate and the TFT substrate of a liquid crystal display. The lower half of the pixels in the color filter substrate and the upper half of the pixels in the TFT substrate are dried by heating by irradiating it with a laser beam. The remaining sections are thereafter dried naturally. The pretilt angle of the molecules of the liquid crystal material in contact with the sections dried by heating with the laser beam is small and the pretilt angle of the molecules which are in contact with the section dried naturally is large, enabling the viewing angle to be widened.
