Abstract: A display device includes a display module, a light source, a light-guiding substrate including at least a side surface adjacent to the light source, and an optical filter provided on the light-guiding substrate. The optical filter includes a first insulating layer including a first sub-insulating layer, a second sub-insulating layer, and a third sub-insulating layer, a second insulating layer provided on the first insulating layer to be in contact with the second sub-insulating layer, and a first liquid crystal layer which selectively transmits or reflects light provided from the light-guiding substrate. The first liquid crystal layer is disposed in each of first cavities which are defined as closed spaces enclosed by the first sub-insulating layer, the third sub-insulating layer, and the second insulating layer.

Abstract: A backlight unit includes a light source which generates light; a light guide plate which guides the light from the light source and emits guided light through an upper thereof; and an optical member disposed on the upper surface of the light guide plate. The optical member includes: a plurality of first insulating patterns into which the guided light from the upper surface of the light guide plate is incident; and a second insulating layer which covers the first insulating patterns to define an upper surface of the optical member through which light exits toward a display panel. Each of the first insulating patterns includes: a bottom portion extended from the upper surface of the light guide plate; and a sidewall portion upwardly extending from a boundary of the bottom portion, the sidewall portion inclined at an angle relative to the upper surface of the light guide plate.

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.
