Therefore, in the first light emitting member 10a, the second light emitting member 10b and the third light emitting member 10c according to the example shown in FIG. 26, the appearance of each selective light emitting area 142a in the Y direction is the same as the example shown in FIG. The upper width may be gradually narrowed from the first light emitting member 10a to the third light emitting member 10c. Therefore, it is possible to obtain a sense of uniformity in the apparent shape and size of the plurality of selected light emitting regions 142a.
