  • Patent number: 8319212
    Abstract: The present invention provides a light-emitting element and a light-emitting device which have high contrast, and specifically, provides a light-emitting device whose contrast is enhanced, not by using a polarizing plate but using a conventional electrode material. Reflection of external light is suppressed by provision of a light-absorbing layer included between a non-light-transmitting electrode and a light-emitting layer. As the light-absorbing layer, a layer is used, which is obtained by adding a halogen atom into a layer including an organic compound and a metal oxide. Further, the light-absorbing layer is formed also over a region in which a thin film transistor for driving a light-emitting element is formed, a region in which a wiring is formed, and the like, and thus light is extracted from the side opposite to the region in which the TFT is formed, thereby reducing reflection of external light.
