ABSTRACT:
A substrate for a liquid crystal display (LCD) device includes: gate and data lines crossing each other to define a pixel region on a substrate; a thin film transistor adjacent to where the gate and data lines cross, the thin film transistor including a gate electrode, a semiconductor pattern, a source electrode and a drain electrode; a black matrix corresponding to the gate and data lines and the thin film transistor; a first insulating layer disposed on the black matrix and including first and second portions, the first portion corresponding to the pixel region and having a first thickness, and the second portion having a second thickness smaller than the first thickness; a color filter pattern disposed on the first insulating layer and corresponding to the first portion; a first insulating layer disposed on the color filter pattern including first and second portions, the first portion corresponding to the color filter pattern and has a first thickness, and the second portion having a second thickness smaller than the first thickness; and a pixel electrode disposed over the color filter pattern and being connected with the thin film transistor.
