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 present invention provides a display panel and a display device thereof, which relate to the field of display technology and are used to avoid the problem of stealth between light-emitting elements of different colors in an OLED display panel. The display panel includes a base substrate; the base substrate is provided with a plurality of first signal lines extending in a row direction and a plurality of second signal lines extending in a column direction, and the intersection of the first signal lines and the second signal lines defines pixels The circuit area, the pixel circuit area includes a pixel circuit; the substrate substrate is also provided with a plurality of sub-pixel areas, each sub-pixel area includes a light-emitting element, and the pixel circuit provides a driving signal for the light-emitting element; the light-emitting element includes an anode, a light-emitting layer and a A cathode; a spacer is arranged between the anode and the first signal line; the direction perpendicular to the base substrate is a first direction, in the first direction, the anode, the first signal line and the spacer overlap each other, and the spacer, The anode and the first signal line are disposed in different layers from each other. The above-mentioned display panel is suitable for use in a display device.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device thereof. 【Background technique】 [0002] Compared with many display panels, an 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 thinner and lighter in size, but also lower in power consumption than other display devices, which helps to improve the battery life of display devices. mainstream product. [0003] At present, a common OLED display panel includes an organic light-emitting element whose emission color is red, an organic light-emitting element whose emission color is green, and an organic light-emitting element whose emission color is blue. In the preparation process, considering the cost saving and the saving of preparation steps, the same mask wil...
