Abstract
An object of the present invention is to realize a light emitting device having low power consumption and high stability, in addition to improve extraction efficiency of light generated in a light emitting element. At least an interlayer insulating film (including a planarizing film), an anode, and a bank covering an edge portion of the anode contain chemically and physically stable silicon oxide, or are made of a material containing silicon oxide as its main component in order to accomplish a light emitting device having high stability. Generation of heat in a light emitting panel can be suppressed in addition to increase in efficiency (luminance/current) of a light emitting panel according to the structure of the present invention. Consequently, synergistic effect on reliability of a light emitting device is obtained.
