The invention discloses a semiconductor light-emitting element. The light-emitting element comprises a semiconductor light-emitting sequence, wherein the semiconductor light-emitting sequence comprises a first conductive type semiconductor layer, a light-emitting layer and a second conductive type semiconductor layer, and one side of the second conductive type semiconductor layer is a light-emitting surface. The light-emitting element is characterized in that the light-emitting surface comprises a plurality of independent grooves, bottoms of the grooves are located in the second conductive type semiconductor layer, the area, outside the grooves, of the light-emitting surface is a light transmission blocking area, and side walls of the grooves are inclined relative to the thickness direction of the semiconductor light-emitting sequence. 一种半导体发光元件，其包括半导体发光序列，半导体发光序列包括第一导电类型半导体层、发光层和第二导电类型半导体层，第二导电类型半导体层一侧为出光面，其特征在于:出光面上包括多个独立凹槽，凹槽的底部位于第二导电类型半导体层中，凹槽之外的出光面的区域为光透射阻挡区域，所述的凹槽的侧壁相对于半导体发光序列的厚度方向倾斜的。
