摘要

The present invention relates to a method for forming the light emitting pattern of a light emitting diode such as an organic light emitting diode, a quantum dot light emitting diode, a perovskite light emitting diode, etc., and a donor substrate for forming a light emitting pattern. A donor substrate having a light to heat conversion layer and a hydrophobic thin film pattern is provided. The donor substrate includes a base substrate having optical transparency; a groove pattern layer which is disposed on the upper surface of the light to heat conversion layer and has a groove pattern and a protrusion pattern adjacent to the groove pattern and dividing the groove pattern; and a hydrophobic thin film pattern which is located on the upper surface of the protrusion pattern of the groove pattern layer. It is possible to form a precise and uniform light emitting pattern on a target substrate.
