PROBLEM TO BE SOLVED: To provide an image display device capable of displaying a high quality image always giving an optimal visual feeling even with an input video signal biased in the signal level distribution. SOLUTION: The maximum signal level, the minimum signal level, and the average signal level of an input video signal Fv are detected and calculated by a video signal level measuring circuit and are stored in CPU 2 as basic condition data, a plurality of organic light emitting elements 10 each arranged at cross-points of scanning lines and drive lines arranged in a matrix form are emission-controlled according to a set signal level and emission time based on the basic condition data so that the optimal visual feeling can be obtained for the picture display to a video data Dv of pixels corresponding to the input video signal Fv, for example, even when the whole signal level is low and a dark video signal is inputted, a bright image without much black is displayed, and thus, it becomes possible to display an exact high quality image for which the optimal visual feeling is always obtained, to an input video signal of any signal level distribution. |
