Abstract
Disclosed herein is a method for manufacturing edge emission type EL device arrays. A substrate carrying individually formed EL device arrays is coated with a transparent film. The film is etched to form terminals through exposure of the edges of block terminals and to make contact holes reaching an upper electrode layer of the EL devices. The contact holes are then covered with a conductive layer that is etched to form common electrodes conductive to predetermined edge emission type EL devices within each block.
