<p>PROBLEM TO BE SOLVED: To provide a liquid crystal display in which manufacturing yield is improved by preventing peeling. SOLUTION: When difference in stress in the tensile direction between a gate insulating film 6 and a gate electrode 7 exceeds approximately 2×109 dyn/cm2 or more, only the gate electrode 7 tends to deform and the surrounding of the gate electrode 7 is peeled off from the gate insulating film 6. Regarding the stress in the pressing direction, a force works in the direction of pressing the peripheral edge of the gate electrode 7 on the gate insulating film 6 and adhesion is increased. When the stress difference in the pressing direction exceeds 3×109 dyn/cm2 or more, the central part in the gate electrode 7 is peeled off from the gate insulating film 6. The stress difference between the gate electrode 6 and the gate insulation film 7 is suppressed to within the range of -3×109 dyn/cm2 or +2×109 dyn/cm2 to suppress the generation ratio of defective.</p> |
