Abstract: A display apparatus including a light source; a display panel; an optical sheet. The light source including a first light source substrate and a second light source substrate spaced apart from the first light source substrate in a width direction. The light source is mounted on the light source module and a width of a region defined by half of a maximum brightness of a light profile of the light source, is set as a full width at half maximum brightness. A distance between a center of the first light source substrate in the width direction and a center of the second light source substrate in the width direction is referred to as a pitch, the full width at half maximum brightness of the light source and the pitch satisfy: 1.0 ≤ full width at half maximum brightness/pitch ≤ 2.0..
