Abstract:
A method of manufacturing on a substrate a liquid crystal display having a gate bus line, a data bus line, and a switching element with a drain electrode, the method comprising the steps of:forming a protection layer over the substrate to cover the gate bus line, the data bus line, and the switching element; depositing a first layer on the protection layer, the first layer having a thermal expansion coefficient smaller than that of the protection layer; depositing a second layer on the first layer, the second layer having a thermal expansion coefficient that is substantially the same as that of the first layer; depositing a photoresist layer on the second layer, the photoresist layer being developed into a desired pattern; removing portions of the second layer on the first layer to form a desired pattern of the second layer using the photoresist layer as a mask; removing portions of the first layer using the patterned second layer as a mask to form a desired pattern of the first layer; and removing the second layer remaining on the patterned first layer.
