Abstract:
1. A method for manufacturing a liquid crystal display device, comprising: forming first common electrodes on a first substrate; forming gate lines and data lines to cross each other to define RGBW sub-pixels on the first substrate; forming a thin film transistor at each crossing of the gate and data lines; forming a passivation layer on an overall surface of the first substrate including the thin film transistor; forming pixel electrodes on the passivation layer, each pixel electrode having at least one slit; forming black matrices on a second substrate; forming RGBW color filter layers above the black matrices corresponding to respective RGBW sub-pixels; forming an overcoat layer on an overall surface of the second substrate including the color filter layers; the forming the second common electrodes on the overcoat layer to correspond only to each W sub-pixel; attaching a second substrate to the first substrate, wherein the first and second substrate face each other; and forming a liquid crystal layer between the first and second substrates.
