Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel includes a color filter substrate and a thin film transistor array substrate facing each other; a color filter layer and black matrix formed on the color filter substrate, wherein the black matrix is formed for preventing light leakage; an electrode on at least one of the two substrates for generating an electric field; a plurality of gate lines and data lines crossing each other on a first side of the thin film transistor array substrate defining pixel region; a thin film transistor formed at each crossing between the gate lines and the data lines; and a liquid crystal layer formed between the color filter substrate and the thin film transistor array substrate; a backlight assembly for irradiating light onto the liquid crystal panel; and a reflection layer formed on a rear surface of the thin film transistor array substrate to increase an amount of light incident onto the liquid crystal panel, wherein the reflection layer is formed on the rear surface of the thin film transistor array substrate corresponding to the black matrix, and has the same pattern as the black matrix, and wherein the reflection layer reflects light, which is irradiated from the backlight assembly toward the black matrix to the backlight assembly and changes the light outgoing path so as to increase a condensation rate of light irradiated toward the light transmission region of the liquid crystal panel, wherein the reflective layer is formed of an opaque metal layer.
