Abstract: A display apparatus includes: a light guide panel; a light source unit including a plurality of light emitting diode elements arranged in an X direction at a position facing a side surface of the light guide panel; and a lens unit arranged between the light guide panel and the light source unit. The light source unit, the lens unit and the light guide panel are arranged in a Y direction crossing the X direction. The lens unit includes: a light entering surface facing the light source unit; and a light emitting surface being opposite to the light entering surface and facing the side surface of the light guide panel. The light entering surface of the lens unit is a concave surface extending in the X direction.
