Patent ID: 8208095

Claim:
A method for manufacturing a display substrate, the method comprising: forming a polarizing layer on a base substrate, the polarizing layer including a polarizing pattern comprising a plurality of carbon nano-tubes, wherein forming the polarizing layer comprises: forming a photoresist on the base substrate; patterning the photoresist to form a plurality of openings in the photoresist; forming a hydrophobic layer in the openings; removing the patterned photoresist layer; performing a hydrophilic treatment on portions of the base substrate adjacent portions of the base substrate on which the hydrophobic layer is formed; and forming a water layer on the base substrate, wherein the water layer flows away from the portions of the base substrate on which the hydrophobic layer is formed to the portions of the base substrate on which the hydrophilic treatment was performed; and forming a pixel layer having a plurality of pixel units on the base substrate.
