Abstract:
1. A manufacturing method of a liquid crystal display device, comprising: forming a gate line and a data line on a substrate, the gate and data lines crossing each other to define a pixel region; forming a thin film transistor at a crossing portion of the gate and data lines; forming a passivation layer on the substrate and the thin film transistor; forming a transparent conductive layer on the passivation layer; forming a first photosensitive layer on a portion of the transparent conductive layer over the thin film transistor; forming a second photosensitive layer contacting and directly on the transparent conductive layer and the first photosensitive layer; patterning the second photosensitive layer and the first photosensitive layer to form a photosensitive pattern and a columnar spacer exposing a portion of the transparent conductive layer, wherein the photosensitive pattern includes first and second patterns, the first pattern is disposed directly over the columnar spacer, and the second pattern is disposed in the pixel region; forming a pixel electrode by patterning the transparent conductive layer exposed by the photosensitive pattern and the columnar spacer, wherein the pixel electrode is disposed directly under the second pattern; and removing the photosensitive pattern, wherein the first photosensitive layer is a positive type, and the second photosensitive layer is a negative type, wherein patterning the second photosensitive layer and the first photosensitive layer includes:
