摘要： The present invention provides a lightweight, thin light-emitting device having a new structure which has a plurality of display screens. Further, the invention provides a dual emission type display device which can perform a pure black display and can achieve high contrast. According to the invention, at least, both electrodes of a light-emitting element (an anode and a cathode of a light-emitting element) are highly light-transmitting at the same level, and a polarizing plate or a circularly polarizing plate is provided, thereby conducting a pure black display that is a state of no light-emission and enhancing the contrast. Moreover, unevenness of color tones in displays of the both sides, which is a problem of a full-color dual emission type display device structure, can be solved according to the invention.
