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.
Claims7
A manufacturing method of a display panel, comprising steps as follows:
- providing a functional layer with a plurality of blind holes, wherein each of the blind holes is surrounded by the functional layer;
- preparing a transfer printing device, wherein the transfer printing device comprises a stage, a plate cylinder, and a transfer printing plate disposed on a side wall of the plate cylinder, wherein the stage is horizontally movable to carry a substrate, and a plurality of grooves are defined in the transfer printing plate, and each of the grooves is surrounded by the transfer printing plate;
- and
- coating an alignment liquid on the substrate by using the transfer printing device to form an alignment film with through holes formed by the grooves of the transfer printing plate, wherein each of the through holes is surrounded by the alignment film, and the through holes directly overlap the blind holes.
