EL DISPLAY DEVICE AND FABRICATING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive, highly precise EL display device. SOLUTION: After forming a positive electrode 102, a luminescent layer 102 and a negative layer 104 on a substrate 101, alkali metal elements or alkaline earth metal elements are selectively added to form electron transport regions 106a to 106c. If voltage is applied to the resulting structure at a desired level, the luminescent layer will emit light only at portions where the electron transport regions were formed. Thus, a desired image display can be achieved.
