摘要： A display panel includes an upper display substrate including a first pixel area, a second pixel area, a third pixel area, and a light blocking area surrounding the first, second, and third pixel areas and a lower display substrate including a light emitting element. The upper display substrate includes a base substrate, a first bank overlapping the light blocking area and disposed on the base substrate, a second bank overlapping the light blocking area and disposed on the base substrate, a bridge bank disposed on the base substrate between the first bank and the second bank, and an organic material pattern whose at least a portion is disposed on the bridge bank. The display panel has improved reliability.

摘要： A display device (100) includes a lower substrate (110), a sub-pixel structure, an optical filter layer (530), a colour filter layer (510), an upper substrate (410), and an alignment structure (600). The lower substrate has a display area (10) and a peripheral area (20) surrounding the display area. The sub-pixel structure is disposed in the display area on the lower substrate. The optical filter layer (530) is disposed on the sub-pixel structure. The colour filter layer (510) is disposed on the optical filter layer. The upper substrate (410) is disposed on the colour filter layer. The alignment structure is disposed in the peripheral area on a bottom surface of the upper substrate, and contains a material that is the same as a material forming the optical filter layer and the colour filter layer.

摘要： Provided is a display panel including first substrate including a first pixel region, a second pixel region, a third pixel region, and a light-blocking region defined therein.
The first substrate includes a base layer; a first color filter layer overlapping the light-blocking region and the first pixel region; a light blocking layer overlapping the light-blocking region; a second color filter layer overlapping the second pixel region; a third color filter layer overlapping the third pixel region; and a step compensation layer disposed on one surface of the light-blocking layer and configured to cover at least a portion of the light-blocking region adjacent to the first pixel region in a plan view.
