Embodiment approach 1
[0061] based on Figure 1 to Figure 8 One embodiment of the present invention will be described below.
[0062] Next, an organic EL display device will be described as an example of the display device according to the present embodiment.
[0063]
[0064] figure 1 It is a diagram schematically showing the schematic structure of the light-emitting layer unit 33 of the organic EL display device 1 of the present embodiment together with the principle of light emission. figure 2 (a) is a diagram showing the principle of light emission in the sub-pixel 3B of the organic EL display device 1 of this embodiment, figure 2 (b) is a diagram showing the principle of light emission in the sub-pixel 3G of the organic EL display device 1 of this embodiment, figure 2 (c) is a diagram showing the principle of light emission in the sub-pixel 3R of the organic EL display device 1 of the present embodiment. image 3 It is a plan view schematically showing the pixel arrangement of the org...
Embodiment approach 2
[0245] mainly based on Figure 9 (a) to (c) describe another embodiment of the present invention as follows.
[0246] In this embodiment, differences from Embodiment 1 will be described, and components having the same functions as those described in Embodiment 1 will be denoted by the same reference numerals, and description thereof will be omitted. It goes without saying that the same modification as that of Embodiment 1 is possible in this embodiment.
[0247]
[0248] The organic EL display device 1 of the present embodiment has the same configuration as the organic EL display device 1 of the first embodiment except that a red phosphorescent light-emitting material is used as the light-emitting material of the red light-emitting layer 34R. Therefore, the cross-sectional view showing the schematic structure of the organic EL display device 1 of the present embodiment and the Figure 4 same. A cross-sectional view showing a schematic structure of the light-emitting layer...
Embodiment approach 3
[0264] mainly based on Figure 10 Still another embodiment of the present invention will be described below.
[0265] In this embodiment, differences from Embodiments 1 and 2 will be described, and components having the same functions as those described in Embodiments 1 and 2 will be assigned the same reference numerals and descriptions thereof will be omitted. It goes without saying that in this embodiment, the same modifications as in Embodiments 1 and 2 are possible.
[0266]
[0267] Figure 10It is a cross-sectional view showing an example of a schematic configuration of the organic EL display device 1 of the present embodiment. Figure 10 express with image 3 An example of the schematic structure of one pixel region corresponding to the L1-L2 line section of the organic EL display device 1 shown.
[0268] The organic EL display device 1 of the present embodiment is a bottom emission type organic EL display device in which light emitted from the light-emitting laye...
