Abstract: A display device is provided with an image processing circuit that outputs a pixel value of each pixel to a pixel driving circuit, the pixel driving circuit that inputs a pixel voltage to each of pixels based on the pixel value of each of the pixels, and a control circuit that detects a defective pixel. Here, the image processing circuit corrects the pixel value of the defective pixel in the image data to be displayed which is input to the image processing circuit, to a pixel value for black, and then outputs each pixel value of the image data to be displayed in which the pixel value of the defective pixel is corrected to the pixel value for black, to the pixel driving circuit.

Abstract: A display device allows an optimal display mode to be selected in accordance with the form of use, so that the total power consumption is decreased. The display device includes an organic EL display panel for displaying a monochromatic image; and a color shutter glass unit including a pair of shutters. The pair of shutters are each controllable to be in a light transmissive state for a first color, a second color and a third color or in a light non-transmissive state. The pair of shutters corresponding to left and right glasses are each controllable in synchronization with display of an image on the organic EL display panel, so that one of a monochromatic image display mode, a color image display mode, a monochromatic three-dimensional image display mode, and a color three-dimensional image display mode is selected.
