Abstract: A backlight unit including a light guide plate (LGP), a light source module disposed adjacent to an incident surface of the LGP and configured to irradiate light to the incident surface, and a light control member disposed between the light source module and the incident surface, in which the light control member includes a reflection preventing layer disposed adjacent to the light source module and configured to prevent reflection of light, a base substrate disposed on the reflection preventing layer and configured to scatter or diffuse light transmitted through the reflection preventing layer, and a light adjusting filter disposed on the base substrate and configured to filter light including a first wavelength among light provided by the light source module.

Abstract: A display device may include a display panel, at least one light source disposed on one side of the display panel, a circuit board to drive the light source, a light guide plate in which light emitted from the light source is incident into a surface and is emitted to another surface, and a lower frame to support the display panel and to accommodate the light source and the light guide plate. The lower frame may include a base substrate, a digitizer disposed on the base substrate, and a dummy digitizer pattern disposed on the base substrate and spaced apart from the digitizer. The circuit board may be disposed between the digitizer and the dummy digitizer pattern, and the lower frame may be bent and extend around the light source.

Abstract: A wavelength conversion member may include a first substrate and a second substrate that overlaps the first substrate. The wavelength conversion member may further include a wavelength conversion layer disposed between the first substrate and the second substrate in a first direction. The wavelength conversion member may further include a first hydrophobic membrane that overlaps at least one of the first substrate, the second substrate, and the wavelength conversion layer in a second direction perpendicular to the first direction.
