Abstract
A method for manufacturing a lower substrate of a liquid crystal display device is disclosed and more particularly, a method for manufacturing a color filter layer on a lower substrate is disclosed. This method is achieved by using a photosensitive insulating layer as a passivation layer or an overcoat of a thin film transistor to reduce the number of masks, or of photographic steps. The photosensitive insulating layer used in the method has the characteristics of both photoresist and passivation layers so as to protect a thin film transistor from moisture and oxygen. In addition, the number of masks, or of photographic steps used in this method can be further reduced by ink-jet printing a color filter layer or by half-tone mask technique.
