  • Publication number: 20160268363
    Abstract: When a hollow structure in which a light-emitting element is provided between a pair of substrates is used in order to prevent oxygen or moisture from reaching the light-emitting element, light leakage to an adjacent pixel easily occurs as compared to a structure in which a space between a pair of substrates is filled with a resin such as an adhesive. In order to reduce light leakage to an adjacent pixel in the hollow structure, a light-blocking spacer is formed over a partition to keep the distance between the pair of substrates uniform. The cross-sectional shape of the light-blocking spacer is a trapezoid having a lower side shorter than an upper side.

    Abstract: A method for exposing an electrode terminal covered with an organic film in a light-emitting device without damaging the electrode terminal is provided. In a region of the electrode terminal to which electric power from an external power supply or an external signal is input, an island-shaped organic compound-containing layer is formed and the organic film is formed thereover. The organic film is removed by utilizing low adhesion of an interface between the organic compound-containing layer and the electrode terminal, whereby the electrode terminal can be exposed without damage to the electrode terminal.
