DISPLAY DEVICE
According to one embodiment, a display device includes a first pixel provided in a display area which displays an image, a transmissive area provided in the display area, and a partition which includes a conductive lower portion and an upper portion having an end portion protruding from a side surface of the lower portion, and is provided in the display area. The first pixel includes a plurality of subpixels surrounded by the partition. The transmissive area includes a plurality of sub-areas which are surrounded by the partition and transmit at least part of light which enters the transmissive area.
1 . A display device comprising:
a first pixel provided in a display area which displays an image;
a transmissive area provided in the display area; and
a partition which includes a conductive lower portion and an upper portion having an end portion protruding from a side surface of the lower portion, and is provided in the display area, wherein
the first pixel includes a plurality of subpixels surrounded by the partition, and
the transmissive area includes a plurality of sub-areas which are surrounded by the partition and transmit at least part of light which enters the transmissive area.
2 . The display device of claim 1 , wherein
each of the subpixels includes:
a lower electrode;
an organic layer which covers the lower electrode and emits light based on application of voltage; and
an upper electrode which covers the organic layer and is in contact with the lower portion of the partition, and
the lower electrode is not provided in the sub-areas.
3 . The display device of claim 2 , wherein
neither the organic layer nor the upper electrode is provided in the sub-areas.
4 . The display device of claim 3 , wherein
each of the subpixels further comprises an optical adjustment layer which covers the upper electrode, and
the optical adjustment layer is not provided in the sub-areas.
5 . The display device of claim 4 , wherein
each of the subpixels further comprises a first sealing layer formed of an inorganic insulating material which covers the optical adjustment layer, and
the first sealing layer is not provided in the sub-areas.
6 . The display device of claim 1 , further comprising a rib layer which is located under the partition and is formed of an inorganic insulating material having a pixel aperture in each of the subpixels, wherein
the sub-areas overlap the rib layer.
7 . The display device of claim 6 , wherein
the rib layer has an aperture which overlaps at least one of the sub-areas.
8 . The display device of claim 7 , wherein
the aperture includes a plurality of linear apertures arranged in the sub-area.
9 . The display device of claim 7 , wherein
the aperture includes a plurality of dot apertures dispersed in the sub-area.
10 . The display device of claim 6 , further comprising a first resin layer which covers the display area, wherein
the first resin layer is in contact with the rib layer in the sub-areas.
11 . The display device of claim 10 , further comprising a second sealing layer formed of an inorganic insulating material which covers the first resin layer.
12 . The display device of claim 11 , further comprising a second resin layer which covers the second sealing layer.
13 . The display device of claim 1 , wherein
a number of subpixels is equal to a number of sub-areas.
14 . The display device of claim 13 , wherein
the subpixels include a first subpixel, a second subpixel and a third subpixel, and
the sub-areas include first, second and third sub-areas which are provided in a same positional relationship as a positional relationship of the first, second and third subpixels.
15 . The display device of claim 14 , wherein
the partition includes:
a first part which defines the first subpixel, the second subpixel and the third subpixel; and
a second part which defines the first sub-area, the second sub-area and the third sub-area.
16 . The display device of claim 15 , wherein
the first part and the second part have a same shape.
17 . The display device of claim 1 , wherein
a number of subpixels is different from a number of sub-areas.
18 . The display device of claim 17 , wherein
the number of sub-areas is greater than the number of subpixels.
19 . The display device of claim 1 , further comprising:
a plurality of pixel circuits which are provided in the display area and drive the subpixels, respectively; and
a plurality of lines which supply voltage or a signal to the pixel circuits, wherein
at least one of the lines overlaps the partition and does not overlap the sub-areas.
20 . The display device of claim 19 , wherein
the display area has a first area including a second pixel, and a second area including the first pixel and the transmissive area, and
the first pixel is smaller than the second pixel.
