Patent ID: 7663723

Claim:
A liquid crystal display device comprising: a first substrate and a second substrate; a gate line and a data line on the first substrate crossing each other to define a pixel region; a switching element in the pixel region; a black matrix formed along the gate line and the data line on the first substrate, the black matrix having a portion that covers an upper side of the gate line and extends into the pixel region; a color filter located at the pixel region; a planarization film formed on an entire surface of the substrate and covering the black matrix and the color filter; a common electrode and a pixel electrode above the planarization film for generating an electric field within the pixel region; a common line having a first portion covering the upper side of the whole area of the gate line and a second portion covering an upper side of the whole area of the data line, the common electrode extending from the first portion of the common line; and a liquid crystal layer formed between the first and second substrates.
