ABSTRACT:
An active matrix type liquid crystal display comprising a liquid crystal layer containing liquid crystal molecules, a pair of substrates arranged to be facing each other with the liquid crystal layer interposed there between, a pair of polarizers arranged outside of the substrates, active elements composed of semiconductor active layers and insulating layers, having scanning electrodes and signal electrodes which are arranged between one of the pair of substrates and the liquid crystal layer, pixel electrodes formed between one of the pair of substrates and the liquid crystal layer and connected to the active elements, light shielding layers for preventing the active elements from being illuminated by incident light, and counter electrodes arranged on the same plane as the light shielding layers taking one of said pair of substrates as a pair of substrates and the active element, between the liquid crystal layer and the active element, or between another one of the pair of substrates and the liquid crystal layer, in a manner facing the scanning electrode of the active element.
