PURPOSE: To provide a laser emission display comprising a laser projector and a power supply generating the driving current separated from each other through a signal line in which the number of signal lines is decreased while miniaturizing the laser projector.

CONSTITUTION: When a laser unit 2 is driven, a positive power supply +V is connected with the emitter of a transistor Q4 and a pulse is fed to the base thus projecting a laser beam. When a display LED 12 is driven, a negative power supply -V is connected with the emitter of a transistor Q5 and a clock pulse is fed to the base thereof thus projecting a display light. When the laser unit 2 and the LED 12 are driven while shifting the phase of driving pulse, a power supply part C1 and a laser projector T2 can be connected through two signal lines La, Lb.
