Abstract: PROBLEM TO BE SOLVED: To provide a display device capable of balancing securement of display performance with securement of manufacturability. SOLUTION: Thicknesses DR, DG and DB of barrier layers 163R, 163G and 163B within lower electrode layers 16R, 16G and 16B are made different from one another among three organic light emitting elements 30R, 30G and 30B (DR>DG>DB). By utilizing an interference phenomenon of light caused by the difference of resonance lengths among the three organic light emitting elements 30R, 30G and 30B based on the difference among the thicknesses DR, DG and DB, white light generated in a layer 18 including a luminescent layer is converted to three color light rays, that is, red light ER, green light EG, and blue light EB. Since it is not necessary to color-code the layer 18 including a luminescent layer by using a metal mask, a display size can be increased and, since it is not necessary to convert white light to three color light rays ER, EG and EB by using only a high-concentration and relatively thick color filter for color conversion, utilization efficiency of light is secured.

Abstract: PROBLEM TO BE SOLVED: To provide a display apparatus compatible in the insurance of display performance and in the insurance of manufacturing capabilities. SOLUTION: Thicknesses DR, DG and DB of barrier layers 163R, 163G and 163B among lower electrode layers 16R, 16G and 16B are different from each other among three organic light emitting elements 30R, 30G and 30B, wherein DR>DG>DB. By using interference phenomenon of light due to the differences of resonance length among the three organic light emitting elements 30R, 30G ad 30B based on the differences among the thicknesses DR, DG and DB, white light generated in a layer 18 including the light emitting layer is converted into three color lights, i.e. red light ER, green light EG and blue light EB. The display size can be enlarged since it is not necessary to selectively apply the layer 18 including the light emitting layer with a metal mask, and utilization efficiency of light is secured since it is not necessary to convert the white light into the three color lights ER, EG and EB with using only color filter for color conversion having a high density and a relatively large thickness.
