Display apparatus

Abstract

A display apparatus includes a first substrate, a light emitting device and a first insulating layer. The light emitting device and the first insulating layer are disposed on the first substrate. The first insulating layer has an opening, and the light emitting device is disposed in the opening. A portion of a light emitted by the light emitting device passes through the first substrate. An angle between a side wall of the opening and the first substrate is greater than or equal to 60°, and less than or equal to 150°.
