Abstract:
A liquid crystal display having a pair of substrates at least one of which is transparent and a liquid crystal layer held between said pair of substrates,wherein on one of said pair of substrates a display region is provided including a plurality of semiconductor elements disposed in a matrix,wherein each of said plurality of semiconductor elements comprises: first, second, third and fourth electrodes; a pair of first conductivity type semiconductor layers separated from each other and connected to said second and said third electrodes, respectively; an intrinsic semiconductor layer provided in contact with both layers of the pair of first conductivity type semiconductor layers; a second conductivity type semiconductor layer provided in contact with said intrinsic semiconductor layer; an insulating film interposed between said first electrode and said intrinsic semiconductor layer; and said fourth electrode is connected to said second conductivity type semiconductor layer which is provided in contact with said intrinsic semiconductor layer, andwherein a forward bias is applied between said fourth electrode and said second electrode of a semiconductor element when an on-voltage is applied to said first electrode thereof.
