<p>PURPOSE:To enhance reliability by partially forming a plurality of end-face light emitting type EL elements and forming a protective coat with light transmissivity on the entire surface of a substrate including these end-face light emitting type EL elements. CONSTITUTION:Conductive layers 16' and 17' are formed on a substrate 15, and are etched to form a block electrode 17, on which an EL element layer 21 and an upper electrode layer 22 are laminated and formed in that order. The layers 21 and 22 are patterned to partially form a plurality of end-face light emitting type EL elements. A protective coat 28 with light transmissivity is formed on the entire surface of a substrate 15 including these end-face light emitting type EL elements, and is etched to form a terminal part exposing the end of the electrode 17 and the upper electrode layer 22, and a contact hole 33. A conductive layer is formed so as to cover the contact hole 33, and is etched to form a common electrode 31 energized with prescribed EL elements in each block. The EL light emitting element is covered with the protective coat 28 at a next stage for partial formation, and the time when the cut surface of the EL element comes into contact with atmosphere is short.</p> |
