Abstract
Provided is a self light emitting type display device which can correct variations in characteristics of self-emitting elements arranged in a display panel, a driver IC which drives lighting of the self-emitting elements, and the like.A self-emitting module 1 is composed of a display panel 2 on which a plurality of self-emitting elements are arranged, a flexible circuit board 3 whose one end portion is connected with the display panel, a memory 10 which is loaded on the circuit board 3 and in which data for adjusting light emission intensities of the self-emitting elements is stored, and a drive unit 5 which is loaded also on the circuit board and which is equipped with a function of generating the drive current which is for adjusting the light emission intensities of the respective light emitting elements based on the data stored in the memory. Since the memory 10 and the drive unit 5 are loaded in the self-emitting module 1, in a state in which the self-emitting module is an individual module body before the module 1 is connected with a main body substrate 6 side, intensity adjustment of the respective light emitting elements can be performed, and adjustment work for intensity pr…
