LIGHT EMITTING ELEMENT, LIGHT EMITTING DEVICE, LIGHTING DEVICE, BACKLIGHT AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/012086
Kind Code:
A1
Abstract:
This light emitting element is provided with: a semiconductor core (201) of a first conductivity type; and a semiconductor layer (203) of a second conductivity type, which is arranged around the outer peripheral surface of the semiconductor core. At least one of the lateral surfaces constituting the outer peripheral surface of the semiconductor core is entirely covered by the semiconductor layer (203); and another lateral surface has an exposed portion (205) that is not covered by the semiconductor layer (203) and is exposed. An xy cross-section of the light emitting element has a length L1 in the x direction and a length L2 in the y direction, and L1 and L2 satisfy the relational expression 2 × L2 ≤ L1 ≤ 1,000 × L2. The exposed portion (205) has a length L3 in the y direction and a length L4 in the z direction, and L3 is from 60% to 100% of L1.
