IMAGE DISPLAY DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a circuit-containing thin film transistor type image display device having circuits constituted of high performance thin film transistors on a display pixel block and a peripheral circuit block and small circuit special purpose area and to provide a simple method for manufacturing the same.

SOLUTION: The image display device comprises a display pixel block and peripheral circuit blocks including four corners of the display device on a substrate. The image display device further comprises a circuit made of the thin film transistors in which the longitudinal direction of crystal grains and the current direction of a polycrystalline silicon film anisotropically crystal grown and provided on the entire or partial surface of the display pixel block and the circuit block coincide in such a manner that the directions are aligned in the horizontal or vertical direction in the block, and the blocks in which the horizontal and vertical directions are allowed to be disposed in a mixed state as seen on the same straight line.
