摘要:
A surface-emitting light source includes a substrate including a light emitting region where plural light emitting points are disposed and a non-light emitting region located around the light emitting region; and a lens array including plural lenses and a non-lens region around the plural lenses. The substrate and the lens array are directly bonded with each other at the non-light emitting region and the non-lens region such that the plural light emitting points and the plural lenses face each other, and the lens array has a linear expansion coefficient not greater than a linear expansion coefficient of the substrate.
