A substrate includes a base, a pixel defining layer, a plurality of electrode pairs, and a plurality of light-emitting devices. The pixel defining layer is disposed on the base, and includes a plurality of through holes. At least one electrode pair includes a first electrode and a second electrode that are disposed at least on a hole wall of one of the through holes and at least partially opposite to each other, and the first electrode and the second electrode are insulated from each other. One of the plurality of light-emitting devices includes a liquid functional layer disposed in the through hole. The liquid functional layer is in direct contact with the first electrode and the second electrode. The liquid functional layer includes a liquid light-emitting layer configured to emit light.

Substrate and display panel

The present disclosure provides an organic thin film and a method for preparing the same, a display device, and an optical device, in which the method includes: providing a base substrate; forming an isomerization generating layer on the base substrate, the isomerization generating layer including a first region and a second region; adding a precursor solution on a surface of the isomerization generating layer away from the base substrate, and allowing surface energy of the second region to be greater than surface energy of the first region, so as to form the organic thin film from the precursor solution, the precursor solution being at least partially located in the second region.
