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 at least a portion of which is disposed on the bridge bank forming a column spacer. The display panel has improved reliability.

摘要： A display device may include a first transistor, a second transistor, a first electrode, a second electrode, a first optical filter, and a second optical filter. No intervening transistor may be positioned between the first transistor and the second transistor. The first electrode may be electrically connected to the first transistor. The second electrode may be electrically connected to the second transistor. The first optical filter may overlap the first electrode and may have a first circular perimeter in a plan view of the display device. The second optical filter may overlap the second electrode, may have a polygonal perimeter in the plan view of the display device, and may be spaced from the first optical filter.

摘要： A display apparatus for providing an image through an array of a plurality of pixels includes: an optical panel which converts light of the light-emitting panel into light of another color or transmit the light of the light-emitting panel. The optical panel includes: a substrate; a plurality of color filters arranged over the substrate; a first light-blocking layer arranged in the non-pixel area; a second light-blocking layer arranged in the non-pixel area and on the first light-blocking layer; and a color-converting layer and a transmission layer each overlapping a corresponding color filter from among the plurality of color filters in a plan view. Each of the first light-blocking layer and the second light-blocking layer defines a plurality of holes corresponding to the plurality of pixels, and a width of a hole of the second light-blocking layer is greater than a width of a hole of the first light-blocking layer.

摘要： A display apparatus includes a light source, a display panel, a light guide member, and an optical member. The light source is configured to generate light. The display panel is configured to display an image. The light guide member includes at least one surface adjacent to the light source. The optical member is between the light guide member and the display panel. The optical member includes a low refractive layer, a first cover layer, and a light conversion layer. The low refractive layer is on a light output surface of the light guide member and includes side surfaces. The first cover layer is on the low refractive layer and surrounds at least a portion of the side surfaces of the low refractive layer. The light conversion layer is on the first cover layer and is configured to covert a wavelength band of incident light.
