PROBLEM TO BE SOLVED: To achieve fine display effect by achieving a ppi value, that is an actual value similar to a striped arrangement in AMOLED, without changing the pixel size and resolution in an organic light-emitting element.SOLUTION: A red light-emitting layer 10 and a blue light-emitting layer 30 having closest luminous efficiency are arranged in the same sub-pixel, and the light-emitting region of the red light-emitting layer and the light-emitting region of the blue light-emitting layer are placed to overlap each other. The aperture ratio of subpixel is increased by controlling the light generated from each primary color light-emitting layer by means of different positive electrode layers 10a, 20a, 30a, and the light-emitting area of each subpixel is also increased.SELECTED DRAWING: Figure 5 |
