Abstract: A display device includes a display area, a peripheral area disposed outside the display area, and a sealing area disposed outside the peripheral area, a first base substrate, a second base substrate facing the first base substrate, a color filter layer disposed under the first base substrate, a bank layer disposed under the color filter layer, and a sealing member disposed between the bank layer and the second base substrate in the sealing area. The bank layer includes bank patterns defining an opening disposed at least in the sealing area, and the sealing member fills the opening. Each of the bank patterns includes a first surface adjacent to the color filter layer and a second surface opposite to the first surface and adjacent to the sealing member. A width of the second surface is greater than a width of the first surface.

Abstract: A display device includes a first light emitting element diode and a second light emitting diode which are disposed on a first base substrate, a bank layer disposed under a second base substrate facing the first base substrate, including a first opening overlapping the first light emitting diode in a plan view and a second opening overlapping the second light emitting diode in a plan view, and having a first part and a second part, a transmitting layer disposed inside the first opening, and a first color conversion layer disposed inside the second opening. The first part and the second part have different thicknesses in a thickness direction of the second base substrate.

Abstract: A method of manufacturing a display device, which is provided using an inkjet apparatus that provides a liquid composition including a scatterer, includes performing j scanning stages to provide a first composition to i unit display areas among n unit display areas (j is a natural number equal to or greater than 2), and performing a first compensation-scanning stage to provide the first composition to first to (i−1)-th unit display areas among the n unit display areas. The i unit areas of the first head unit provide the first composition to the first unit display area to an i-th unit display area among the n unit display areas in a first scanning stage among the j scanning stages. The first head unit is shifted in the second direction by one unit display area in every scanning stage of the j scanning stages.

Abstract: A color conversion substrate includes: a bank having a first open region and a second open region; a color conversion layer in the first opening region, the color conversion layer including color conversion particles; a first partition wall partitioning the second opening region into a central region and a peripheral region surrounding the central region, the first partition wall having a polygonal shape with n vertices in a plan view where n is a natural number greater than or equal to 3; and n second partition walls extending from the n vertices of the first partition wall to an edge of the second opening region, respectively, to partition the peripheral region into n sub-regions.
