Photoresist Employing Photodimerization Chemistry and Method for Manufacturing Organic Light Emitting Diode Display Using the Same

A method for manufacturing an organic light emitting diode display comprising:

• forming an electrode on a substrate;
• depositing an organic light emitting layer on the electrode;
• depositing a photoresist on the organic light emitting layer, the photoresist including a copolymer formed by the process comprising:
• providing a first monomer represented by formula (1) and a second monomer represented by formula (2)
• and
• forming the copolymer from the first monomer and the second monomer, where x:y is a ratio of the first monomer to the second monomer and x:y is selected from the range of x:y=1:0.1 to x:y=1:1;
• patterning the photoresist into a patterned photoresist by exposing the photoresist to ultraviolet light using a mask;
• patterning the organic light emitting layer into a patterned organic light emitting layer using the patterned photoresist;
• and
• stripping the patterned photoresist.
