Problems solved by technology
[0004] In the prior art, in order to fix the Micro-LED device during transportation and transfer, the Micro-LED device needs to be bonded to the inorganic layer on the substrate. Correspondingly, the Micro-LED needs to be broken many times. The connection between the device and the inorganic layer will cause damage to the Micro-LED device and affect the performance of the Micro-LED device

The invention discloses a substrate, a transfer substrate, a display panel and a manufacturing method thereof, and a display device, and relates to the technical field of display, the substrate comprises a substrate main body, and one side of the substrate main body is provided with at least one groove; the grooves comprise a first groove and a second groove which are communicated with each other, in the same groove, the first groove and the second groove are arranged in the first direction, and the first direction is parallel to the direction of the plane where the substrate is located; in the direction perpendicular to the plane where the substrate is located, the grooves do not penetrate through the substrate body, and the depth of the first grooves in the direction perpendicular to the plane where the substrate is located is smaller than that of the second grooves in the direction perpendicular to the plane where the substrate is located. The invention is beneficial to the placement of micro devices.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a substrate, a transfer substrate, a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Light Emitting Diode (LED) is an optoelectronic semiconductor element that can convert current into a specific wavelength range. Its light-emitting principle is the energy difference between electrons moving between n-type semiconductors and p-type semiconductors, releasing energy in the form of light , so light-emitting diodes are called cold light sources, which have the advantages of low power consumption, small size, high brightness, easy matching with integrated circuits, and high reliability, and are widely used as light sources. Moreover, with the maturity of LED technology, the technology of directly using LEDs as self-luminous display point pixels of Mini LED (submillimeter LED) displays or Micro LED (ie micro LED) disp...
