Electrowetting display unit and method for manufacturing thereof

A method for manufacturing an electrowetting display unit, comprising:

• providing a first substrate and a second substrate;
• disposing a first conductive layer on a surface of the first substrate, and the surface of the first substrate facing the second substrate;
• disposing a second conductive layer on a surface of the second substrate, and the surface of the second substrate facing the first substrate;
• disposing a polymer layer on the first conductive layer, the polymer layer including a siloxane containing a light-induced cross linkable group and a Si—H bond, and the molecular weight of the siloxane being equal to or greater than 5000;
• exposing a part of the polymer layer to a light so as to form a plurality of hydrophobic sections;
• forming a hydrophilic section by developing with a developing agent, the hydrophilic section surrounding the plurality of hydrophobic sections, and the hydrophilic section and the plurality of hydrophobic sections forming a pattern layer together;
• and
• disposing polar liquid and non-polar liquid between the pattern layer and the second conductive layer.
