Abstract: Color filters of R, G and B consisting of a negative resist film are simultaneously exposed by use of a photomask intercepting light for the regions connected to the transparent pixel electrodes after the source electrodes. Then, the color filters are simultaneously developed. Since the color filters consist of a negative resist film, the regions of the color filters corresponding to the light-intercepted regions, that is, the regions connected to the transparent pixel electrodes after the source electrodes are removed by the development, so that openings are formed.

Abstract: A liquid crystal display panel comprises a TFT substrate unit having a thin film transistor (TFT), a control electrode connected to the TFT, a flattening film covering the control electrode, and a pixel electrode having a cross slit and formed on the flattening film and insulated from the control electrode. An opposite substrate unit has an opposite electrode facing the pixel electrode at a predetermined position. A liquid crystal layer disposed between the TFT substrate unit and the opposite substrate includes liquid crystal molecules having negative dielectric aeolotropy. When voltage is supplied between the control electrode and the opposite electrode, an electric field is generated between them. The electric field divides the liquid crystal layer into four domains in each pixel according to the cross slit formed in the pixel electrode.
