Abstract
According to one embodiment, a display device includes a substrate having a display area, pixels in the display area and each including a lower electrode, an upper electrode, and an organic layer between the lower and upper electrodes, a dummy pixel area surrounding the display area and including dummy pixels, and a partition provided in the display area, the dummy pixel area and an outer circumference area surrounding the dummy pixel area, the partition including a lower portion and an upper portion. Further, the partition has slits provided in the display area and the dummy pixel area. The slits are not provided at a boundary between the dummy pixel area and the outer circumference area.

A display device, comprising:
- a substrate having a display area for displaying images;
- a plurality of pixels provided in the display area and each including a lower electrode, an upper electrode located above the lower electrode, and an organic layer located between the lower electrode and the upper electrode and emitting light based on application of voltage;
- a dummy pixel area surrounding the display area and including a plurality of dummy pixels not displaying images;
- and
- a partition provided in the display area, the dummy pixel area and an outer circumference area surrounding the dummy pixel area, the partition including a lower portion having conductivity and an upper portion having an end portion protruding relative to a side surface of the lower portion, wherein
- the partition has a plurality of slits provided in the display area and the dummy pixel area, and
- the slits are not provided at a boundary between the dummy pixel area and the outer circumference area.
