发明名称 ACTIVE MATLIX TYPE ELECTROOPTICAL DEVICE
摘要 <p>PURPOSE:To improve the in-plane uniformity of an action characteristic by changing the area of a switching element according to a distance from a driving circuit. CONSTITUTION:The area of the switching element part, in which a picture element electrode 5 overlaps with a row electrode 4, is made comparatively small at a point C close to a driving circuit connecting part 3 and made succes sively large as it goes away from points B and A and the connecting part 3. As it goes away from the connecting part 3, a voltage given to the switching element by the line resistances of the row electrode and column electrode is made relatively low, and a current to flow in the element is increased to the contrary by the degree to increase the area of the switching element. Both effects offset each other, a charge quantity to flow into a picture element is made approximately fixed, and respective picture elements on a substrate show approximately fixed action characteristics to the voltage impressed from the connecting part 3. Thus, the in-surface uniformity of the action characteristics can be improved.</p>
