Abstract
A liquid crystal display device includes first board having a reference voltage electrode on one surface, a second board having, on a main surface, a lattice of conductive stripes, a plurality of pairs of a transistor and a picture element electrode, each pair being disposed at each crossing point of the conductive stripes and the transistors being thin film transistors using polycrystalline or amorphous silicon, and a driving circuit for driving the conductive stripes, the driving circuit being formed in a monocrystalline silicon in a form of semiconductor integrated circuit directly connected to the conductive stripes, and a liquid crystal interposed between the one surface of the first board and the main surface of the second board.
