1. A display apparatus comprising:
a display panel; and
a light source module configured to provide light to the display panel,
wherein the light source module comprises:
a substrate; and
a plurality of light emitting diodes mounted on the substrate and arranged along a first direction and a second direction perpendicular to the first direction; and
wherein a first distance between the plurality of light emitting diodes spaced apart in the first direction and a second distance between the plurality of light emitting diodes spaced apart in the second direction satisfy the following expression:
(first distance)≤1.1*(second distance),
wherein when the first distance is less than or equal to 1.1 times the second distance and when an optical distance between a diffuser plate and the substrate is in a first range, a ratio of a pitch in the first direction to the optical distance satisfies a first condition, and
wherein when the first distance is less than or equal to 1.1 times the second distance and wherein when the first distance is less than or equal to 1.1 times the second distance and when the optical distance is in a second range, the ratio of the pitch in the first direction to the optical distance satisfies a second condition.
