    Abstract: A organic light emitting diode display including an organic light emitting display panel displaying an image, and a lower passivation film attached to a bottom of the organic light emitting panel and including a polymer resin and an antistatic agent, wherein the lower passivation film includes a plurality of stress adjustment patterns disposed to be adjacent to each other wherein decreasing the bending interval between the bending stress adjustment patterns formed at the lower passivation film processed with the antistatic agent and attached at the position corresponding to the bending portion of the organic light emitting panel, thereby selectively minimizes the stress of the bending portion of the organic light emitting panel, therefore, asymmetry of strains of the bending portions of the organic light emitting display panel can be prevented to remove a picture abnormality, and static electricity may be prevented.

    Abstract translation: 一种有机发光二极管显示器，包括显示图像的有机发光显示面板和附着在有机发光面板的底部并包括聚合物树脂和抗静电剂的下钝化膜，其中下钝化膜包括多个 的应力调整图案彼此相邻，其中减少在用抗静电剂处理并附着在与有机发光面板的弯曲部分相对应的位置处形成的下钝化膜处形成的弯曲应力调节图案之间的弯曲间隔， 从而有选择地使有机发光面板的弯曲部的应力最小化，因此可以防止有机发光显示面板的弯曲部的应变的不对称性，去除图像异常，并且可以防止静电。

    Abstract: A display device includes a touch panel (TP), a transparent adhesive member (TAM) on a surface of the TP, a touch printed circuit board (TPCB), and a display panel (DP) on a surface of the TAM. The TP includes a sensing portion and a pad side portion (PSP) on a side of the sensing portion. The TPCB includes a contact portion (CP) attached to a surface of the PSP. The DP includes a substrate, an optical film (OF) on a surface of the substrate, and a bending protection layer (BPL) on a side of the OF on the surface of the substrate. The surface of the PSP includes a connection area attached to the CP and a non-connection area not attached to the CP. The OF is spaced from the BPL with a gap disposed therebetween. The TAM overlaps, in a thickness direction, with the TPCB and the gap.
