Abstract:
A method for manufacturing a liquid crystal display comprising the steps of:forming a switching element on a substrate; coating an organic passivation layer on the substrate having the switching element using a photosensitive material; exposing and developing the passivation layer to form a contact hole exposing at least one electrode of the switching element while causing a remaining portion of the passivation layer to remain in the contact hole; etching the passivation layer to remove the remaining portion of the passivation layer in the contact hole with an etching gas which includes at least one selected from the group consisting of CF4+H2, CxFy+H2, CxFy+CxFyHz, CxFy+H2, CxFy+H2 and CxFyHz; and forming a pixel electrode connected to the at least one electrode of the switching element through the contact hole on the passivation layer.
