TRANSFLECTIVE LIQUID CRYSTAL DISPLAY, AND ELECTRONIC EQUIPMENT HAVING THE SAME, PARTICULARLY REGARDING TO ACCORDING THICKNESS OF LIQUID CRYSTAL THROUGH WHICH LIGHT PASSES IN REFLECTIVE DISPLAY FORM AND IN TRANSMISSIVE DISPLAY FORM

摘要

PURPOSE: A transflective liquid crystal display, and an electronic equipment having the same are provided to secure the desirable thickness of liquid crystal in a reflective display form as well as in a transmissive display form by adjusting thickness of an insulation film and depth of a depressed part, thereby improving the display quality. CONSTITUTION: Liquid crystal(5) is filled between substrates(2,3) opposite to each other. A common electrode is formed at a liquid crystal layer of one substrate. A plurality of TFT(Thin Film Transistor)s(10) are formed at a liquid crystal layer of the other substrate, and the TFTs are covered with an insulation film(20) so that a plurality of reflective pixel electrodes(11) electrically connected with the TFTs are formed on the insulation film. A transmissive hole(23) is formed at a part of the pixel electrode. A dug part(22) is formed on the insulation film positioned at a lower part of the transmissive hole. A transparent electrode(19) placed at a lower part of the dug part and electrically connected with the TFT is directly placed on the substrate. The liquid crystal is introduced into a depressed part(27) so that thickness of the liquid crystal at a dug part forming area is different from thickness of the liquid crystal at the pixel electrode forming area.
