  • Publication number: 20210104592
    Abstract: An organic light emitting diode display device includes a substrate, a pixel structure, a lower blocking member, an upper blocking member, and a metal member. The substrate includes a display area and a peripheral area. The pixel structure is in the display area on the substrate. The lower blocking member is in the peripheral area on the substrate and surrounds the pixel structure, and includes a first side surface adjacent to the pixel structure, a second side surface, and a top surface. The upper blocking member is on the top surface and the second side surface of the lower blocking member, and constitutes a first blocking structure with the lower blocking member. The metal member is between the first blocking structure and the substrate while making contact with a bottom surface of the upper blocking member on the second side surface of the lower blocking member.
