  • Publication number: 20210134924
    Abstract: A display panel includes a base layer, a circuit layer, a light emitting element, a pixel defining film, an encapsulation layer, and a first dam. The base layer may include a display area and a non-display area adjacent to the display area. The encapsulation layer may include a first inorganic film, an organic film, and a second inorganic film. The first dam may be disposed between the first inorganic film and the second inorganic film, and outside the organic film. The first dam may overlap the non-display area and the pixel defining film on a plane. Therefore, in the display panel of an embodiment, the non-display area may be reduced.
