    • A light-emitting element array can be manufactured without the separation of a metal reflection layer. The light-emitting element array includes a plurality of light-emitting element portions provided on a substrate, at least one space of the spaces between adjacent light-emitting element portions being electrically separated from each other, wherein the metal reflection layer is provided on the substrate and under the plurality of light-emitting element portions, and a resistive layer for electrical separation between the light-emitting element portions is provided between the plurality of light-emitting element portions and the metal reflection layer. The plurality of light-emitting element portions are divided into a plurality of blocks. Each of the blocks includes a plurality of light-emitting portions. The electrical separation between the light-emitting portions can be made as electrical separation between adjacent light-emitting element portions in adjacent and different blocks.
    • 可以在不分离金属反射层的情况下制造发光元件阵列。 发光元件阵列包括设置在基板上的多个发光元件部,相邻的发光元件部之间的空间的至少一个空间彼此电分离,其中金属反射层设置在 基板和多个发光元件部分之下,并且在多个发光元件部分和金属反射层之间设置用于在发光元件部分之间进行电气分离的电阻层。 多个发光元件部分被分成多个块。 每个块包括多个发光部分。 发光部之间的电气分离可以在相邻的和不同的块之间的相邻的发光元件部分之间进行电分离。
