Embodiment Construction

[0040] Hereinafter, a display panel and a display device including the display panel according to exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0041] In general, display devices may be classified into top emission type display devices and bottom emission type display devices according to the direction of light emission.

[0042] In the following description, for convenience of explanation, a bottom emission type display device is described as an example of a display device according to an exemplary embodiment of the present disclosure. However, it should be understood that the essential features will apply equally to top emission display devices.

[0043] image 3 is an equivalent circuit diagram of a pixel region of an organic light emitting display (OLED) device according to an exemplary embodiment of the present disclosure. In the following, reference will be made to image 3 The manner in which ...

Abstract

The present invention discloses an organic light emitting display panel and an organic light emitting display device comprising the same. The organic light-emitting display panel can improve the color purity and color gamut by reducing optical interference between adjacent pixel areas. A black bank layer is disposed on a planarization layer, such that it is possible to suppress light emitted from an organic emission layer from being reflected via various paths to be scattered to adjacent pixel areas. In addition, the black bank layer comes in contact with a color filter layer via holes formed in the planarization layer to thereby reduce optical interference between adjacent pixel areas. In this manner, the color purity and color gamut of displayed images can be improved, and a display device with excellent image quality can be implemented.

Description

technical field [0001] The present disclosure relates to an organic light emitting display panel and a display device including the organic light emitting display panel. More particularly, the present disclosure relates to an organic light emitting display panel capable of improving color purity and color gamut by reducing light interference between adjacent pixel regions and a display device including the organic light emitting display panel. Background technique [0002] With the development of an information-oriented society, various demands on display devices are increasing. In this regard, display devices having various display panels such as liquid crystal display panels, plasma display panels, organic light emitting display panels, and the like are being developed and released. [0003] Among them, an organic light emitting display (OLED) device using an organic light emitting display panel is a self-luminous display device. Therefore, unlike liquid crystal display ...
