Problems solved by technology
[0004] However, since the turn-on voltages of the three light-emitting elements with different light-emitting colors are different, when the light-emitting element with a higher turn-on voltage is turned on, the carriers move laterally through the common film layer, causing the remaining light-emitting colors and light-emitting elements that have not been turned on to steal light. , not only increases power consumption, but also affects the display effect
[0005] Therefore, how to avoid the problem of light-stealing between light-emitting elements of different colors in the OLED display panel, thereby reducing power consumption and improving the display effect is the main technical problem currently faced by the industry.

The invention provides a display panel and a display device thereof, which relate to the technical field of display and are used for avoiding the problem of stealing light between light emitting elements of different colors in an OLED display panel. A display panel includes a substrate; The substrate is provided with a plurality of first signal lines extending in the row direction and a pluralityof second signal lines extending in the column direction, wherein the first signal lines and the second signal lines intersect to define a pixel circuit region, and the pixel circuit region includes apixel circuit; A substrate is further provide with a plurality of sub-pixel regions, each sub-pixel region include a light emitting element, and a pixel circuit provides a driving signal for that light emitting element; The light emitting element comprises an anode, a light emitting layer and a cathode which are stacked in sequence; A gasket is arranged between the anode and the first signal line; The direction perpendicular to the substrate is a first direction in which the anode, the first signal line and the gasket overlap with each other, and the gasket, the anode and the first signal line are arranged in different layers between each other. The display panel is suitable for use in a display device.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device thereof. 【Background technique】 [0002] Compared with many display panels, the OLED (Organic Light-Emitting Diode, hereinafter referred to as OLED) display panel has many advantages such as active light emission, high contrast ratio, and no viewing angle limitation. OLED display panels are not only lighter and thinner in size, but also lower in power consumption than other display devices, which helps to improve the battery life of display devices. Therefore, OLED display panels are widely used in the field of display technology and will become the future of display devices. mainstream products. [0003] Currently, a common OLED display panel includes an organic light emitting element with a red light emitting color, an organic light emitting element with a green light emitting color, and an organic light emitting element with a b...
