  • Publication number: 20240276827
    Abstract: A display device includes a base layer having a plurality of light-emitting regions and a non-light-emitting region disposed adjacent to the plurality of light-emitting regions, and a color filter layer disposed on the base layer. The color filter layer includes a first color filter that transmits a first color light, a second color filter that transmits a second color light, the first color light and the second color light being different from each color, and a third color filter that transmits a third color light, the first color light, the second color light, and the third color light being different from each other. The first to third color filters overlap each other in the non-light-emitting region in a plan view, and in the third color filter, a measurement opening is defined in a region overlapping the non-light-emitting region in a plan view.

  • Publication number: 20230363232
    Abstract: A color conversion panel includes a substrate including a display area including a color conversion layer, a first pixel area, a second pixel area, and a non-pixel area, and a plurality of color filter layers on the substrate. The color filter layers include a first color filter layer in the first pixel area and defining in the non-pixel area, a first alignment pattern, and a first opening spaced from the first alignment pattern, the first pixel area and the second pixel area, and a second color filter layer in the second pixel area, covering the first alignment pattern of the first color filter layer and defining in the non-pixel area a second alignment pattern which overlaps the first opening of the first color filter layer and exposes a portion of the first color filter layer at the first opening, to outside the second color filter layer.

  • Patent number: 10473985
    Abstract: A display apparatus includes a first substrate, a color filter, a gap maintaining pattern, a column spacer, and a blocking dam. The first substrate includes a display area and a peripheral area surrounding the display area. The color filter is disposed in the display area. The gap maintaining pattern is disposed in the peripheral area in a same layer as the color filter. The column spacer is disposed on the color filter. The blocking dam is disposed in a same layer as the column spacer and overlaps the gap maintaining pattern. The difference between the gap of the first and second substrates in the display area and the gap of the first and second substrates in the peripheral area may be decreased.
