An electronic apparatus according to an embodiment comprises: a housing including a first surface, a second surface facing the first surface, and a third surface which surrounds the inner space between the first surface and the second surface; a support member extending from the housing to the outside of the housing to support the housing; a speaker module arranged in the inner space; a first window arranged between the first surface and the speaker module and including a first light-transmitting surface facing the first surface and a first reflective surface facing away from the first light-transmitting surface; a second window arranged between the first window and the first surface and including a second light-transmitting surface facing the first surface and a second reflective surface facing away from the second light-transmitting surface; a light source module arranged between the first window and the speaker module; and a light diffusion member arranged between the light source module and the first reflective surface. The first window may include a light-transmitting region formed on at least a portion of the first reflective surface, through which light diffused by the light diffusion member transmits. Other embodiments are possible.

A lighting module disclosed in an embodiment of the invention may comprise: a substrate; a reflective portion disposed on the substrate; a plurality of light emitting devices disposed on the substrate; a resin layer disposed on the reflective portion and the light emitting devices; and a diffusion layer disposed on the resin layer. The resin layer includes a light-blocking portion that is a recessed area formed to be concave on the upper surface of the resin layer, and the light emitting devices emit light in a first direction, wherein the light-blocking portion may comprise: a first region overlapping the light emitting devices; a second region extending in the first direction from the first region; a third region extending from the second region in the direction of a first side of the substrate; and a fourth region extending from the second region in the direction of a second side of the substrate. The surface area of the second region may be larger than that of the third region or that of the fourth region, and the light-blocking portion may be formed as an air gap.
