Abstract

A display device includes a display panel and a camera module. The display panel displays an image on a first surface, and includes a first substrate, a sub-pixel structure, a reflection pattern, and a transflective reflection pattern. The first substrate included a plurality of pixel regions each having sub-pixel regions, a transparent region, and a reflection region surrounding the sub-pixel regions and the transparent region. The second substrate is disposed on the sub-pixel structure. The reflection pattern is disposed in the reflection region on the second substrate, and exposes the sub-pixel regions and the transparent region. The transflective reflection pattern is disposed on the second substrate, and has an opening exposing at least a portion of at least one transparent region among the transparent regions. The camera module is disposed in the second surface on the display panel, and the second surface is opposite to the first surface.

First claim

What is claimed is:

1. A display device, comprising:
a display panel having a first surface and a second surface which is opposite to the first surface, the display panel displaying an image in the first surface, the display panel including:
a first substrate including a plurality of pixel regions, each of the plurality of pixel regions having sub-pixel regions, a transparent region, a reflection region surrounding the sub-pixel regions and the transparent region, and a sub-pixel structure in each of the sub-pixel regions;
a second substrate facing the first substrate a reflection pattern exposing the sub-pixel regions and the transparent region, and a transflective reflection pattern having an opening exposing at least a portion of the transparent region being disposed on the second substrate; and
a camera module on the second surface of the display panel.

2. The display device of claim 1 , wherein the transflective reflection pattern that is located in the transparent region corresponding to a portion where the camera module is positioned has an opening.

3. The display device of claim 1 , wherein a thickness of the transflective reflection pattern is less than a thickness of the reflection pattern, and a light transmissivity of the transflective reflection pattern is greater than a light transmissivity of the reflection pattern.

4. The display device of claim 1 , wherein the reflection pattern and the transflective reflection pattern are disposed between the second substrate and the sub-pixel structure, and the reflection pattern is interposed between the second substrate and the transflective reflection pattern.

5. The display device of claim 1 , wherein the reflection pattern and the transflective reflection pattern are disposed between the second substrate and the sub-pixel structure, and the transflective reflection pattern is interposed between the second substrate and the reflection pattern.

6. The display device of claim 1 , wherein the reflection pattern and the transflective reflection pattern are disposed on an upper surface of the second substrate which faces the first substrate, and the reflection is interposed between the second substrate and the transflective reflection pattern.

7. The display device of claim 1 , wherein the reflection pattern and the transflective reflection pattern are disposed on an upper surface of the second substrate which faces the first substrate, and the transflective reflection pattern is interposed between the second substrate and the reflection pattern.

8. The display device of claim 1 , wherein the display panel includes a center region and a peripheral region surrounding the center region, and
wherein the camera module is disposed in the center region or the peripheral region.

9. The display device of claim 8 , wherein the camera module is disposed in the center region, and the transflective reflection pattern that is located in the transparent regions corresponding to the center region has an opening that exposes at least a portion of the transparent regions.

10. The display device of claim 1 , wherein the camera module captures an image of an object that is located in front of the first surface of the display panel via the transparent regions of the display panel.

11. The display device of claim 1 , further comprising:
a body surrounding the display panel and the camera module.

12. The display device of claim 11 , wherein the body holds the camera module that is located in the second surface on the display panel.

13. The display device of claim 1 , further comprising:
a moving member coupled to the camera module, the moving member being configured to move the camera module on the second surface of the display panel.

14. The display device of claim 13 , wherein the transflective reflection pattern has an opening that exposes at least a portion of the transparent regions.

15. The display device of claim 14 , further comprising:
a body surrounding the display panel, the camera module, and the moving member.

16. The display device of claim 1 , wherein the sub-pixel structure includes:
a semiconductor element on the first substrate;
a lower electrode on the semiconductor element;
a light emitting layer on the lower electrode; and
an upper electrode on the light emitting layer.

17. The display device of claim 16 , wherein the upper electrode exposes the transparent regions.

18. The display device of claim 17 , wherein the semiconductor element includes:
an active layer on the first substrate, the active layer including source and drain regions;
a gate electrode on the active layer;
a source electrode on the gate electrode, the source electrode being in contact with the source region of the active layer; and
a drain electrode spaced apart from the source electrode, the drain electrode being in contact with the drain region of the active layer.

19. The display device of claim 18 , wherein the semiconductor element further includes:
a gate insulation layer on the first substrate, the gate insulation layer covering the active layer in the sub-pixel region and exposing the transparent regions;
an insulating interlayer on the gate insulation layer, the insulating interlayer covering the gate electrode in the sub-pixel region and exposing the transparent regions; and
a planarization layer on the insulating interlayer, the planarization layer covering the source and drain electrodes in the sub-pixel region and exposing the transparent regions.

20. The display device of claim 19 , wherein a portion of the first substrate that is exposed by the gate insulation layer, the insulating interlayer, and the planarization layer in the transparent regions is defined as a transparent window of the transparent regions.
