Abstract
The disclosed display apparatus eliminates the need of a dedicated inspection jig when inspecting a memory carried on the driving substrate of the display apparatus; a memory inspection can be conducted under conditions for practical use in which TCON reading memory data is operated; and another display inspection (such as a point defect inspection) can be conducted simultaneously with the memory inspection. The display apparatus includes a drive circuit for holding and utilizing operation setting data in the memory, wherein the drive circuit includes: a display data generation section which associates two values of data bits read from the memory with two values of light and shade or different colors and makes image data represented in a line or a rectangle; a switch for selecting the data generated by the display data generation section and input image data; and a switching timing control section which controls timing of switching.
