  • Patent number: 9882131
    Abstract: An organic light emitting diode display including: a plurality of pixel electrodes formed in a display area of a substrate; a pixel defining layer having an opening exposing a part of each of the plurality of pixel electrodes and formed in the display area; a plurality of emission layers formed on the plurality of pixel electrodes; and a common electrode formed on the pixel defining layer and the plurality of emission layers. The pixel defining layer is formed with a smaller thickness farther from the center of the display area.
    Type: Grant

  • Patent number: 9508952
    Abstract: An organic light emitting display device includes a first substrate, a second substrate, and an array of organic light emitting elements formed over the first substrate and interposed between the first and second substrate. The array comprises a pixel defining layer. The organic light emitting display device further includes a recess formed into the pixel defining layer, a sealing member, and a reinforcing member. The sealing member is formed along the edges of the first and second substrates and interconnects the first and second substrates. The reinforcing member comprises a first portion positioned in the recess and a second portion projected outside the recess toward the second substrate such that the second portion of the reinforcing member is capable of supporting the second substrate when the second substrate is pressed toward the first substrate by an external force.
