摘要:
A backlight unit includes a light source substrate on which a light source is mounted, a first light source plate which is disposed on the light source substrate and includes a cylindrical aperture corresponding to the light source, and a second light source plate which is disposed on the first light source plate and includes a partial transmission pattern on a bottom surface thereof. The partial transmission pattern corresponds to the aperture and allows part of light emitted from the light source to pass therethrough.
