A lighting member comprising: a light guide member which is a multi-sided light-transmitting light guide member having a plurality of surfaces and has a light incident portion which is at least one of the plurality of surfaces, a first light exit portion which is at least one other surface opposite to the light incident portion among the plurality of surfaces, and a second light exit portion which is at least one other surface positioned laterally in a direction in which light entering the light incident portion travels toward the first light exit portion, such that the first light exit portion and the second light exit portion emit the light that has entered the light incident portion; a plurality of light emitting diodes disposed at predetermined intervals adjacent to the light incident portion to allow the light to enter the light incident portion; and a mounting board connected to the light guide member and having a surface on which the plurality of light emitting diodes are disposed, wherein a concave-convex portion is formed on a surface of the first light exit portion to mitigate irregularity of a light emitting pattern on the first light exit portion which is caused by the intervals between the plurality of light emitting diodes at the light incident portion, wherein the light guide member comprises a light guide film, the light incident portion comprises one edge surface of the light guide film, the first light exit portion implements a linear light source, and the second light exit portion implements a surface light source, wherein a predetermined pattern is formed on a surface of the second light exit portion to emit a part of the light that enters the light incident portion and travels toward the first light exit portion, wherein the linear light source and the surface light source emit the light simultaneously. a light guide member which is a multi-sided light-transmitting light guide member having a plurality of surfaces and has a light incident portion which is at least one of the plurality of surfaces, a first light exit portion which is at least one other surface opposite to the light incident portion among the plurality of surfaces, and a second light exit portion which is at least one other surface positioned laterally in a direction in which light entering the light incident portion travels toward the first light exit portion, such that the first light exit portion and the second light exit portion emit the light that has entered the light incident portion; a plurality of light emitting diodes disposed at predetermined intervals adjacent to the light incident portion to allow the light to enter the light incident portion; and a mounting board connected to the light guide member and having a surface on which the plurality of light emitting diodes are disposed, wherein a concave-convex portion is formed on a surface of the first light exit portion to mitigate irregularity of a light emitting pattern on the first light exit portion which is caused by the intervals between the plurality of light emitting diodes at the light incident portion, wherein the light guide member comprises a light guide film, the light incident portion comprises one edge surface of the light guide film, the first light exit portion implements a linear light source, and the second light exit portion implements a surface light source, wherein a predetermined pattern is formed on a surface of the second light exit portion to emit a part of the light that enters the light incident portion and travels toward the first light exit portion, wherein the linear light source and the surface light source emit the light simultaneously.
