Method for manufacturing fringe field switching mode liquid crystal display
This invention provides a method for manufacturing a fringe field switching mode liquid crystal display. The method includes the steps of: depositing a transparent metal layer on a transparent insulating layer and forming a counter electrode by etching the transparent metal layer according to a first mask process; depositing an insulating layer on the counter electrode and the substrate; depositing a first opaque metal layer on the insulating layer and forming a gate line, a common electrode line and a pad by etching the first opaque metal layer according to a second mask process; depositing a gate insulating layer, an a-Si layer and an n+ a-Si layer in turn on a resultant and defining an active region of thin film transistor by etching the n+ a-Si layer and the a-Si layer according to a third mask process; depositing a transparent metal layer on the resultant and forming a pixel electrode of a comb shape by etching the transparent metal layer according to a fourth mask process; etching the gate insulating layer according to a fifth mask process so that the pad is exposed; forming a source electrode, a drain electrode and data line including a data pad by etching the second opaque metal layer according to a sixth mask process; and forming a passivation layer on the entire resultant and etching the passivation layer according to a seventh mask process so that the data pad is exposed.
