First light shield layer 112 of plate 21 and the first reflecting layer 113 are similar to the configuration of the embodiment of Fig. 3.Remaining it is same or like it
Place, sees previous embodiment, is not repeated to illustrate in this.
Under the configuration of the display panel 21 of each embodiment, using the second pixel cell P2 as example, selfluminous cell
In the light that 121L is issued, only the second light beam L2 can be injected in color conversion unit 111G, and the first light beam L1 is then hidden by first
Light unit 112S2 and/or the second lightproof unit 122S1 are absorbed, therefore correspond to the selfluminous cell of the second pixel cell P2
The light that 121L is issued can't be injected in adjacent the first pixel cell P1 or third pixel cell P3.
In addition, by making multiple first reflector element 113R2 be respectively arranged at color conversion unit 111R, 111G and 111B
At least a side, such as so that every one first reflector element 113R2 is set to the first lightproof unit 112S2 and turn with a wherein color
It changes between unit 111R, 111G or 111B, can further reflect and concentrates light, with improving extraction efficiency.
Furthermore the height (or being thickness) of the first lightproof unit 112S2 is relatively high, therefore can avoid that specific face should be injected
The light (should e.g. inject the light of color conversion unit 111R) of color converting unit is towards other color conversion units (such as color
Converting unit 111G or 111B) it is incident, cause the situation of light mixing to generate and reduce color saturation.Also, the first reflector element
The thickness of 113R2 is relatively thin, in case excessive extraneous light reflects via the first reflector element 113R2 and reduces contrast.

First light shield layer 112 of plate 22 and the first reflecting layer 113 are similar to the configuration of the embodiment of Fig. 3.Remaining it is same or like it
Place, sees previous embodiment, is not repeated to illustrate in this.
Under the configuration of the display panel 22 of each embodiment, using the second pixel cell P2 as example, selfluminous cell
In the light that 121L is issued, only the second light beam L2 can be injected in color conversion unit 111G, and the first light beam L1 is then hidden by first
Light unit 112S2 and/or the second lightproof unit 122S2 are absorbed, therefore correspond to the selfluminous cell of the second pixel cell P2
The light that 121L is issued can't be injected in adjacent the first pixel cell P1 or third pixel cell P3.
In addition, by making multiple first reflector element 113R2 be respectively arranged at color conversion unit 111R, 111G and 111B
At least a side, such as so that every one first reflector element 113R2 is set to the first lightproof unit 112S2 and turn with a wherein color
It changes between unit 111R, 111G or 111B, can further reflect and concentrates light, with improving extraction efficiency.
Furthermore the height (or being thickness) of the first lightproof unit 112S2 is relatively high, therefore can avoid that specific face should be injected
