description	PURPOSE:To obtain the process for production of the dot matrix type LED display device which does not require a lamp house. CONSTITUTION:This process for production consists of a 1st stage for die bonding LED chips 4 to a lower substrate 1 disposed with common electrodes 3, a 2nd stage for fixing an upper substrate 2 disposed with segment electrodes 6 and bored with holes 5 for lamp houses in alignment to the LED chips 4 to the lower substrate 1 by an insulating adhesive, a 3rd stage for wire bonding the LED chips 4 and wiring patterns 61, and a 4th stage for coating the LED chips 4 and wires 8 with a transparent resin only when the protection thereof is needed.
