Abstract: Disclosed is an organic light emitting display device including an anode, a cathode, a plurality of organic layers and a partition member. The plurality of organic layers is disposed between the anode and the cathode, where at least one layer is separated to minimize current leakage into neighboring pixels. The partition member is disposed between the neighboring pixels and configured to separate the plurality of organic layers. The least one separated layer includes a charge generation layer. Because at least one layer is separated, current leakage into neighboring pixels can be minimized. Accordingly, defects resulting from light leakage and the mixing of colors of light from neighboring pixels may be reduced and display quality is enhanced.
Abstract translation: 公开了一种包括阳极，阴极，多个有机层和分隔构件的有机发光显示装置。 多个有机层设置在阳极和阴极之间，其中至少一层被分离以最小化到相邻像素中的电流泄漏。 分隔构件设置在相邻像素之间并且被配置为分离多个有机层。 至少一个分离层包括电荷产生层。 因为至少一层被分离，所以可以将流入相邻像素的电流最小化。 因此，可能降低由漏光引起的缺陷和来自相邻像素的光的颜色的混合，并提高显示质量。

Abstract: The present disclosure relates to a display device including a piezoelectric film type actuator, the display device having a structure in which a groove is provided in a rear surface of a metal layer for supporting and encapsulate a rear surface of a display panel and the piezoelectric film type actuator is disposed in the groove. Accordingly, the display device may reduce the overall thickness and improve heat dissipation performance.
