PURPOSE:To improve the light emitting efficiency of a blue-color LED without a reflecting plate such as a cup by effectively utilizing the light emitted from the side surface of a light emitting element utilizing a gallium-nitride-based compound semiconductor, and taking out the light to the side of the observing surface. CONSTITUTION:A light emitting element comprises at least a light transmitting substrate 1 and a gallium-nitride-based compound semiconductor 2, which is formed on the light transmitting substrate. With the light transmitting substrate 1 of the light emitting element up, the element is mounted on a lead frame 4. The entire light emitting element is sealed with a resin mold 5. In this blue- color-light emitting diode, the side surface of the light emitting element is cut at an acute angle theta downward from the upper surface of the light transmitting substrate. |
