ABSTRACT:
A chip light emitting device is disclosed. A light emitting chip (LED chip) has overlying semiconductor layers to have a light emitting layer defined between the semiconductor layers. End electrodes are oppositely formed on surfaces of the semiconductor layers in a manner sandwiching the light emitting layer. A substrate has a main surface mounted with the light emitting chip. Terminal electrodes are formed at respective end portions of the substrate. The terminal electrodes is respectively in electrical connection with the end electrodes. The light emitting chip is in a rectangular parallelepiped form so that the light emitting layer thereof assumes in contour a rectangle shape having longer and shorter sides. The light emitting chip is fixed on the substrate in a position that the longer side of the light emitting layer is placed in parallel to the main surface of the substrate. The chip light emitting device obtained is satisfactorily thin in thickness due to the height with respect to the main surface of the substrate is held low without reducing the area of the light emitting layer.
