Document Type and Number:
Japanese Patent JP4042668
Kind Code:
B2
Abstract:
Aspects of the invention can provide a solid state light-emitting element having a solid state light-emitting element chip that emits light in electric current injection, and electrodes for injecting electric current into the solid state light-emitting element chip, the electrodes being disposed on an ejection face of the solid state light-emitting element chip. An optical-path change device, which visually masks electrode forming areas in which the electrodes are formed, can be provided on the ejection face of the solid state light-emitting element chip. Accordingly, irregularity in a projection image due to electrode forming areas can be prevented.
