Inventor: KOIZUMI GENTA
IPC: B41J2/45
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting diode array which has high output and uniform luminous intensity distribution. SOLUTION: A contact layer 42 for an electrode of low resistance of a light- emitting diode is stretched from the outside of a light lead-out region 22 of a light-emitting dot 12 along the central part, so that the injection current in the light leading-out region 22 spreads. An electrode 32 is stretched from the outside toward the central part in a protrusion shape with a length which does not exceed the center of the light lead-out region 22, so that increase of electrode covering ratio in the light lead-out region 22 can be restrained. As a result, the optical output in the light lead-out region 22 can be uniformed, and optical output can be increased significantly.  When electrodes 32 of the light lead-out regions 22 of the neighboring light-emitting dots 12 are shifted with each other in the perpendicular direction to the arrangement direction of the light lead-out regions 22 and arranged staggeredly, the light lead-out regions 22 are aligned in an almost lateral line, so that light-emitting patterns in the alignment direction of the light lead-out regions 22 are relaxed from becoming a staggered configuration.
