Abstract: A display apparatus includes a first substrate in which a plurality of pixel areas and a non-pixel area around the pixel areas are defined, a cavity-defining layer disposed on the first substrate and defining a plurality of cavities corresponding to the pixel areas, an insulating layer disposed on the cavity-defining layer and in the cavities, a liquid crystal layer disposed on the insulating layer in the cavities, and a second substrate disposed on the insulating layer to cover the liquid crystal layer. The liquid crystal layer has a same refractive index as the cavity-defining layer when the liquid crystal layer is not driven. The liquid crystal layer has a greater refractive index than the cavity-defining layer when the liquid crystal layer is driven.

Abstract: A backlight unit includes a light source generating light, a light guide plate guiding the light in an upper direction, and an optical member disposed on the light guide plate to condense the light provided from the light guide plate in the upper direction. A top surface of the light guide plate includes a plurality of circular areas and a peripheral area around the circular areas. Each of the circular areas includes a central circular area and a ring area surrounding the central circular area. The optical member includes a first insulating layer disposed on the light guide plate and spaced apart from the light guide plate by predetermined distances in the ring areas and the peripheral area to define a plurality of cavities, and a second insulating layer disposed on the first insulating layer.

Abstract: A display apparatus and a method of manufacturing a display apparatus are disclosed. A display may include a base substrate, a plurality of pixel rows each of which includes a plurality of pixels arranged both in a first direction and in a second direction, a sealant layer covering the pixel rows, and a trench disposed between the pixel rows. Each pixel row may include a plurality of active cavities arranged along the trench and a drain cavity disposed on at least one end of the trench. A capillary force decreases along the active cavities, the drain cavity, and the trench.
