LIGHT EMITTING DIODE CHIP

摘要

A light emitting diode chip is provided to improve light extraction efficiency and to implement high efficiency large-scale light emitting diode by realizing L/W>10, wherein L is a length of a substrate and W is a width thereof. A light emitting structure(150) is comprised of a first conductive type semiconductor layer(103), an active layer(105), and a second conductive type semiconductor layer(107). The first conductive type semiconductor layer, the active layer, and the second conductive type semiconductor layer are sequentially layered on a substrate(101). A length of the substrate is L and a width thereof is W and then a relationship of L/W>10 is satisfied.
