ABSTRACT:
An "active matrix" type of liquid crystal matrix display panel, in which diodes are employed as switching elements coupled to each liquid crystal display element, photo-sensing elements such as photo-diodes are formed upon the display panel to enable data input to the panel by variation of the electrical characteristics of the photo-sensing elements by selectively varying the level of light incident thereon. The photo-sensing elements, when composed of photo-diodes, can be formed during the same manufacturing process and in the same manufacturing steps as those in which the diode switching elements are formed, so that no appreciable increase in manufacturing cost is entailed by adding such a data input function.
