Abstract

The invention provides a display panel, a manufacturing method thereof, and a display device, and relates to the technical field of display. In the present invention, an electrode connection layer, a flat layer, an anode layer, a pixel defining layer, an organic functional layer and a cathode layer are sequentially arranged on the substrate of the functional display area, and the electrode connection layer includes a plurality of mutually insulated anode connection lines and cathode connection lines. , the anode layer includes a plurality of mutually spaced anodes, two adjacent anodes are connected to the anode connection lines through first vias penetrating the flat layer, the cathode layer includes a plurality of mutually spaced cathodes, and two adjacent cathodes are defined by passing through the pixels The second vias of the layer and the planar layer are connected to the cathode connection line. Since the number of film layers in the functional display area is small, the transmittance of light can be improved. Since the number of traces in the functional display area is small, and the anode and cathode are distributed at intervals, the light transmission area of ​​the functional display area can be increased. , thereby reducing the phenomenon of diffraction coherent superposition, ensuring the normal use of functional devices, and realizing full-screen display.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of display technology, in order to enable users to have a better visual experience, a full-screen design of a display device has become a trend and has been favored by more users. [0003] In the current display device, due to the need to install functional devices such as cameras and sensors, it is often necessary to cut the display device to form an accommodating groove to place the functional devices, such as the design of the notch screen and the water drop screen in the existing display device. [0004] However, the current display device needs to form a accommodating slot to place functional devices, and the accommodating slot occupies a part of the screen. Therefore, the screen ratio of the current display device cannot reach 10...
