    Abstract: A manufacturing method of a backlight unit includes: providing a light emission surface of a light guide plate to include contact areas and a cavity area between contact areas; forming first sacrifice patterns at the cavity area to have a same width as each other; forming a first insulation layer on the first sacrifice patterns and extended to contact the light emission surface at the contact areas; removing the first sacrifice patterns to form a cavity between the light emission surface and the first insulation layer, at the cavity area; and with the cavity at the cavity area, forming a second insulation layer at the cavity area and at the contact areas. The contact areas are arranged spaced apart from each other in the first direction, and a number of the first sacrifice patterns at the cavity area decreases as a distance in the first direction increases.

    Abstract: A display device is provided including a substrate. The substrate includes a pixel area and a light-blocking area. A light-emitting element is arranged in the pixel area of the substrate. An insulating layer is disposed on the substrate. The insulating layer has an opening corresponding to the light-blocking area and an insulating pattern corresponding to the pixel area. A light control pattern at least partially surrounds the insulating pattern of the insulating layer and is arranged in the opening corresponding to the light-blocking area.

    Abstract: 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.
