Abstract

PURPOSE:To make a picture element defect inconspicuous as much as possible and to improve the yield of mass-production by dividing one picture element into at least two elements in an interdigital shape. CONSTITUTION:One picture element is divided into two in a three-interdigital shape in an example shown in a figure. A switching element such as an MIM element is formed on the surface of at least one of two insulating subtrates supporting a liquid crystal layer which contacts the liquid crystal layer to constitute a mechanism which controls the impressed voltage of the liquid crystal layer through picture elements connected to the element by using the element. One signal consists of two elements and its shape is combined to reduce a decrease in yield owing to the accidental formation of a picture element defect.

４分割までが限度である。The present invention provides an active matrix panel in which:
The pixel is divided into at least two parts in a comb-like shape, and the area of the defect is less than half that of an accidental defect (such as a wire break), and its shape makes it less noticeable. Furthermore, if the display is divided into too many parts, the ratio between the area of the MIM element and the pixel area will become small, resulting in poor display characteristics, so the practical limit is to divide the display into four at most.
