Abstract
A display matrix substrate capable of minimizing an adverse effect of a defective switching element developed in the display matrix substrate. On a substrate 10 plural pixel electrodes 2A, 2B are formed in a matrix form. Switching elements 1A, 1B are provided corresponding to the respective plural pixel electrodes 2A, 2B. Voltage is applied to the pixel electrodes 2A, 2B to display an image on the display matrix substrate by successively operating the switching elements. Defective switching element 1A among the plural switching elements is preliminarily detected in a production process. A pixel electrode 2A of the defective switching element 1A is electrically connected to a pixel electrode 2B of a normal switching element 1B adjacent to the defective switching element 1A. Thereby, it is possible to minimize the adverse effect of the defective switching element 1A to a displayed image by making the pixel electrode of the defective switching element 1A operate together with the pixel electrode of the normal switching element 1B adjacent thereto.
