ABSTRACT:
An organic electroluminescent display device includes scanning lines, signal lines, and pixels formed in a matrix, each pixel being at an intersection of each of the scanning lines and each of the signal lines. Each pixel includes a light-emitting element, a light-emitting circuit composed of a thin-film transistor, and a light-receiving circuit composed of a thin-film transistor. When the light-emitting circuit is selected by the scanning line, the light-emitting circuit drives the light-emitting element according to a video signal that is input from the signal line, thereby displaying an image on the pixels formed in the matrix. The light-receiving circuit is selected in a period of time during which the light-emitting circuit does not operate, and outputs a light-receiving signal in accordance with the amount of light incident on the pixel to a different signal line.
