Abstract: A display device includes: a first substrate; a second substrate; a light-emitting element layer on the first substrate and comprising at least one light-emitting element; an encapsulation layer on the light-emitting element layer and comprising at least one inorganic encapsulation layer and at least one organic encapsulation layer; a color conversion-transmitting layer on the encapsulation layer and configured to convert light emitted from the at least one light-emitting element into light having different colors, the color conversion-transmitting layer including quantum dots; a low-refractive inorganic layer on the color conversion-transmitting layer and having a refractive index less than a refractive index of the color conversion-transmitting layer; a color filter layer on a surface of the second substrate opposite to the first substrate; and a filler between the low-refractive inorganic layer and the color filter layer and having a refractive index greater than the refractive index of the low-refractive inorganic layer.

Abstract: A display apparatus includes a pixel-defining layer defining a pixel opening exposing a central portion of a pixel electrode; an opposite electrode disposed over the pixel-defining layer; a bank over the opposite electrode and defining a bank opening overlapping the pixel opening; and a filter-defining layer disposed over the bank and defining a filter opening overlapping the pixel opening. A distance between an upper surface of a portion of the opposite electrode overlapping the pixel opening and a lower surface of the quantum dot layer or the light-transmitting layer is defined as a first distance, a distance between an edge of the filter opening and an edge of the pixel opening in the plan view is defined as a second distance, and a ratio of the second distance to the first distance is greater than or equal to 0.625 and less than or equal to 1.

Abstract: A display device includes: a backlight unit configured to emit light; a first substrate positioned in a path of a light emitted from the backlight unit and including a first pixel and a second pixel displaying different colors from each other; a second substrate facing the first substrate; a light amount control layer positioned between the first substrate and the second substrate; a gate line disposed on the first substrate and extending in a first direction; a storage line disposed on the substrate and spaced apart from the gate line; and a data line disposed on the first substrate and extending in a second direction intersecting the first direction. The first pixel includes a first thin film transistor, a first pixel electrode, and a first light conversion unit. The second pixel electrode includes a second thin film transistor, and a second light conversion unit.
