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 moduleis composed of a display panelon which a plurality of self-emitting elements are arranged, a flexible circuit boardwhose one end portion is connected with the display panel, a memorywhich is loaded on the circuit boardand in which data for adjusting light emission intensities of the self-emitting elements is stored, and a drive unitwhich 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 memoryand the drive unitare loaded in the self-emitting module, in a state in which the self-emitting module is an individual module body before the moduleis connected with a main body substrateside, intensity adjustment of the respective light emitting elements can be performed, and adjustment work for intensity prior to shipping of the product can be made easier.

Self light emitting type display device

A flexible circuit board is provided to prevent unsuccessful interconnection between the wirings of the flexible circuit board and the output terminals of a semiconductor chip, the flexible circuit board having a plurality of sections of wirings of different sizes, each section including a pattern of wirings of the same size. The flexible circuit board has predetermined patterns of wirings on an insulating material base, and the wirings are electrically connected to the output terminals of a semiconductor chip. A pattern of the wirings of the same size forms a first wiring section, while another pattern of the wirings of the same size form a second wiring section. The flexible circuit board is provided with a pattern transition region between the neighboring wiring sections with wirings of different sizes to avoid unsuccessful interconnection which would be otherwise caused by the difference in size between the wirings.
