Abstract
A display apparatus includes a liquid crystal panel; a light source module configured to provide light to the liquid crystal panel; a printed circuit board (PCB) on which the light source module is mounted; and at least one chassis accommodating the liquid crystal panel and the PCB. The light source module includes: a substrate; a reflector positioned on the substrate, and including a curved surface having a shape resulting from rotating a portion of a parabola around a directrix of the parabola, the directrix perpendicular to the substrate; and a plurality of light sources mounted on the substrate along focal points of the parabola of the reflector.
