摘要 To provide a bright and highly reliable light-emitting device. An anode (102), an EL layer (103), a cathode (104), and an auxiliary electrode (105) are formed sequentially in lamination on a reflecting electrode (101). Further, the anode (102), the cathode (104), and the auxiliary electrode (105) are either transparent or semi-transparent with respect to visible radiation. In such a structure, lights generated in the EL layer (103) are almost all irradiated to the side of the cathode (104), whereby an effect light emitting area of a pixel is drastically enhanced. <IMAGE>
