Abstract
A combination of a light emitting element and a light receiving element for monitoring the amount of light emitted from the light emitting element are provided. Also, a control circuit is added for controlling the amount of light emitted from the light emitting element in response to an output of the light receiving element. As their combination constitutes a pixel, a plurality of the pixels are arrayed in a matrix form. With the light emitting elements connected to a line for switching on and off the elements, a resultant display device enables to render the pixels uniform in the luminance. As a result, each pixel can emit a desired level of the illumination determined by an input signal regardless of discrete emission characteristics of the pixel, whereby a reproduced image is free from color blurs and creates highly explicit steps of gradation.
