摘要： A backlight assembly includes a light guide member extending in a direction and having a light incident surface and a light exiting surface. A light source faces the light guide member and supplies light to the light guide member through the light incident surface. A reflecting member reflects light exiting from the light exiting surface of the light guide member. The reflecting member includes a groove receiving the light guide member. A first reflecting portion is disposed under the light guide member and reflects light refracted by the light guide member in an upward direction. A second reflecting portion is disposed on the light guide member and reflects light refracted by the light guide member in a downward direction.

摘要： A manufacturing method of a display apparatus includes providing a backlight unit under a display panel to provide a light to the display panel. The providing of the backlight unit includes disposing a light source on a substrate to emit the light, disposing a mask above the light source, which includes a first opening and a second opening greater than the first opening disposed under the first opening, and providing a transparent resin including a wavelength converting material on the light source through the first and second openings to form a wavelength converting member. A width in a cross section of the wavelength converting member along a direction substantially vertical to the substrate becomes smaller as a distance from the substrate becomes greater.
