Abstract:
A light-source unit for providing light to a display panel includes at least one light-source. The at least one light-source is mounted in a circuit board. A body portion having a housing space houses the circuit board on which the at least one light-source is mounted. A reflection portion reflects light emitted from the at least one light-source. The reflection portion has a parabola shape. The light is reflected by the reflection portion to proceed straight and in a direction perpendicular to a direction that the light is emitted from the at least one light-source.
