Display device and method of manufacturing the same
A display device includes a first area in which a foreign substance is disposed and a second area in which the foreign substance is not disposed. The display device includes a lower panel including a base layer, a display element layer, and an encapsulation layer, an upper panel disposed on the lower panel and including a light control layer and a color filter layer, and a filling layer filling a space between the lower panel and the upper panel. A distance between the display element layer and the light control layer in the first area is greater than a distance between the display element layer and the light control layer in the second area. Accordingly, defects caused by the foreign substance are prevented, and a display quality and a reliability of the display device are increased.
1 . A method of manufacturing a display device, comprising:
detecting a position of a foreign substance in a foreign substance area of a lower panel;
providing an uncured auxiliary filling resin on the lower panel to correspond to the foreign substance area;
providing an uncured filling resin on one surface of an upper panel comprising a light control layer, the uncured filling resin being disposed between the uncured auxiliary filling resin and the upper panel and contacting the uncured auxiliary filling resin;
arranging the lower panel to the upper panel;
curing the uncured auxiliary filing resin together with the uncured filling resin disposed between the lower panel and the upper panel arranged to the lower panel to form a cured filling layer through a light or heat curing process; and
correcting a brightness of an area in which the foreign substance is included.
2 . The method of claim 1 , wherein the correcting of the brightness comprises:
measuring a first brightness of a first area in which the foreign substance is included and a second brightness of a second area in which the foreign substance is not included;
comparing the first brightness of the first area with the second brightness of the second area; and
compensating for the first brightness to obtain a correction brightness with respect to the second brightness.
3 . The method of claim 1 , wherein the uncured auxiliary filling resin is a same material as the uncured filling resin.
4 . The method of claim 1 , wherein the uncured auxiliary filling resin is provided in a dot shape in the foreign substance area adjacent to the foreign substance.
5 . The method of claim 1 , wherein the uncured filling resin is provided in a dot shape over one surface of the light control layer adjacent to the lower panel.
