Abstract: A light emitting device including a first LED sub-unit having a thickness in a first direction, a second LED sub-unit disposed on a portion of the first LED sub-unit in the first direction, each of the first and second LED sub-units comprising a first-type semiconductor layer, a second-type semiconductor layer, and an active layer, a reflective electrode disposed adjacent to the first LED sub-unit and electrically connected to the first-type semiconductor layer of the first LED sub-unit, and a first ohmic electrode forming ohmic contact with the second-type semiconductor layer of the first LED sub-unit, in which the active layer of the first LED sub-unit is configured to generate light, includes AlxGa(1-x-y)InyP (0?x?1, 0?y?1), and overlaps the active layer of the second LED sub-unit in the first direction, and the active layer of the second LED sub-unit includes the same material as the active layer of the first LED sub-unit.

Abstract: A flush toilet capable of correcting a defecation posture, in which a seat disposed on a toilet main body for a user to sit is inclined on the top thereof such that the front where the user's thighs are placed is higher than the rear where the user's hips are placed. Accordingly, smooth defecation is allowed by preventing bending between the intestine and the anus in the body by correcting the posture of a user into a squatting posture such that an angle between the upper body and the thighs of the user is maintained between 35˜50° as if the user were using a squat toilet. Therefore, defecation time is reduced and the user's legs are prevented from becoming numb, thereby improving satisfaction with defecation. Further, intestinal movement is activated during defecation, so smooth defecation is possible, and constipation, hemorrhoids, irritable bowel syndrome, cancers, and other colorectal diseases are prevented.
