Abstract
A display device comprises an inspection circuit for inspecting a data reception related circuit to generate inspection information, an inspection result image generation circuit for generating image data indicating the inspection information, a display switching circuit for superimposing inspection result image data on test video data, and a display unit for displaying the test video data superimposing the inspection result image data. As a result, it is possible to carry out inspection after assembly of the display device without disassembling the display device. This in turn makes it possible to carry out a test in a simple manner on the data reception related circuit inside the display device without changing noise environment inside the display device.
