An array of light emitting elements, formed as regions of a second conductive type in a semiconductor layer of a first conductive type, includes at least one emission-altering element provided for the purpose of altering the amount of light emitted by an adjacent light-emitting element. The emission-altering element may be a trench, an opaque member, or a non-emitting region of the second conductive type. Light-emitting elements in the interior of the array can be made to emit the same amount of light as the light-emitting elements at the ends of the array by placing one emission-altering element between at least every second pair of mutually adjacent light-emitting elements. If the array is divided into blocks, the emission-altering elements can also provide electrical isolation between the blocks.
An array of light-emitting elements, having a light-emitting surface side and a semiconductor layer of a first conductive type, with a plurality of light-emitting regions of a second conductive type disposed in the semiconductor layer, the light-emitting regions emitting light through the light-emitting surface side, the semiconductor layer having an edge positioned so as to reduce a useful intensity of light emitted by a first one of said light-emitting regions that, among said light-emitting regions, is closest to said edge, comprising:
