Abstract
The present disclosure provides a display panel, a manufacturing method thereof, and a transfer printing device. In the embodiments of the present disclosure, at least one groove is defined in a transfer printing plate of the transfer printing device, through holes corresponding to blind holes can be formed in an area corresponding to the grooves, thereby preventing blocking effect of an original alignment film on light passing through the blind holes, increasing light transmittance of the blind holes, and improving an overall performance of devices with the blind holes.
