Abstract
A manufacturing method of a display device includes forming a mask support spaced apart from an edge of a substrate by a first distance, disposing a mask including a transmissive area and a non-transmissive area surrounding the transmissive area on the mask support, determining a display area and a peripheral area positioned at a side of the display area based on at least one of a size of the display area and a width of the non-transmissive area, and forming a light emitting layer in the display area corresponding to the transmissive area and a portion of the peripheral area using the mask.
Claims19
A manufacturing method of a display device comprising:
- forming a mask support spaced apart from an edge of a substrate by a first distance;
- disposing a mask including a transmissive area and a non-transmissive area surrounding the transmissive area on the mask support;
- determining a display area and a peripheral area positioned at a side of the display area based on at least one of a size of the display area and a width of the non-transmissive area;
- and
- forming a light emitting layer in the display area corresponding to the transmissive area and a portion of the peripheral area using the mask.
A display device comprising:
- a substrate including a display area including a light emitting element and a peripheral area positioned on a side of the display area;
- a mask support disposed on the substrate spaced apart from the substrate by a first distance in the peripheral area;
- a via layer disposed on the substrate spaced apart from the mask support;
- and
- a first electrode, a light emitting layer, and a second electrode sequentially disposed on the via layer in a direction in portions of the display area and the peripheral area, wherein
- the first electrode and the second electrode disposed in the display area directly contact the light emitting layer,
- a pixel defining layer is disposed between the first electrode and the light emitting layer disposed in the peripheral area, and
- the display area and the peripheral area are determined based on a size of the display area and a width of the light emitting layer.
