Illumination device

An illumination device comprising:

• a first light guide;
• a second light guide which is adjacent to and connected to the first light guide in a first direction;
• and
• a plurality of light sources which emit light to the first light guide and the second light guide, wherein
• the first light guide comprises a first main surface, a second main surface facing the first main surface, and a first side surface connected to the second light guide,
• the second light guide comprises a third main surface, a fourth main surface facing the third main surface, and a second side surface connected to the first light guide,
• the first side surface further includes a first connection surface and a second connection surface, the first connection surface extending from an end portion of the first main surface to the second main surface and obliquely extending so as to move away from the second side surface, the second connection surface perpendicularly extending from an end portion of the first connection surface to an end portion of the second main surface, and
• the second side surface further includes a third connection surface and a fourth connection surface, the third connection surface extending from an end portion of the third main surface to the fourth main surface and obliquely extending so as to move away from the first side surface, the fourth connection surface perpendicularly extending from an end portion of the third connection surface to an end portion of the fourth main surface.
