Abstract

Disclosed are a liquid crystal display device without a black matrix capable of eliminating light leakage while not decreasing opening degree and reducing production costs and, in addition, a method for fabricating the liquid crystal display device described above. The liquid crystal display device includes: a thin film transistor formed on a first substrate; a first passivation layer formed on the first substrate including the thin film transistor; a color filter layer formed on the first passivation layer; a second passivation layer formed on the first substrate including the color filter layer; a pixel electrode which passes through the second and the first passivation layers, is electrically connected to a part of the thin film transistor and has a lamination structure of transparent metal and opacity metal, wherein the transparent metal part has a width wider than that of the opacity metal part; and a second substrate corresponding to the first substrate.
