Abstract
An image display device which includes a display pixel block and circuit blocks peripheral thereto. Each block has a circuit made of high-performance thin film transistors. The display pixel block and the peripheral circuit blocks including the four corners of the display device are formed on an image display device substrate of circuit-built-in type thin film transistors having a small circuit occupation surface area. A circuit including thin film transistors of a polycrystalline silicon film anisotropically crystal-grown and having crystal grains aligned in its longitudinal direction with a current direction is provided in the whole or partial surface of the display pixel block and circuit blocks. The longitudinal direction is aligned with a horizontal or vertical direction within the block, and blocks aligned in the horizontal and vertical directions can be arranged as mixed when viewed from an identical straight line.
