To decrease the number of layers while keeping or improving the
performance of an EL element, so that the production cost is reduced.
Cathodes (106, 107), a light emitting layer (108), an anode (109), and a
passivation film (110) are formed on pixel electrodes (104, 105).
Thereafter, the vicinity of the interface between the light emitting
layer (108) and the anode (109) are doped with a halogen element through
the passivation film (110) and the anode (109). This leads to formation
of a hole conveying region (111) that functions as a hole conveying
layer, thereby enhancing the light emission efficiency.
