摘要： 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.

摘要： A display apparatus includes a display module which displays an image and a backlight unit disposed below the display module. The backlight unit includes a light source which generates light, a light guide member including a light incident surface which receives the light from the light source and an opposite surface facing the light incident surface in a first direction, and a light collection member which is disposed on the light guide member and receives the light from the light guide member to control a traveling direction of the light so that the light travels to the display module. The light collection member includes an upper light collection layer including upper light collection patterns, each of which has a curved top surface and a lower light collection layer including lower light collection patterns and an intermediate layer which covers the lower light collection patterns.
