Abstract: An optical member includes a first film; a second film disposed to face the first film in a thickness direction; and a plurality of wavelength conversion members disposed between the first and second films and arranged in a direction perpendicular to the thickness direction, where each of the wavelength conversion members has flat surfaces. Flat surfaces of at least two of the wavelength conversion members are not parallel to each other.

Abstract: A backlight unit includes a light guide plate including a first incident surface; a light source module including a first sub-light source module overlapping the first incident surface of the light guide plate in a first direction, where the first sub-light source module provides light to the first incident surface; and a distance adjusting member including a first sub-distance adjusting member overlapping the first incident surface of the light guide plate in the first direction and disposed at a first side of the first sub-light source module and a second sub-distance adjusting member disposed at a second side of the first sub-light source module, which is opposite to the first side of the first sub-light source module. The first sub-distance adjusting member and the second sub-distance adjusting member may move the light guide plate in the first direction.
