Abstract:
1. A liquid crystal display device, comprising: a first transparent substrate; a second transparent substrate facing the first transparent substrate; a gate line arranged on the first transparent substrate along a first direction, the gate line includes a gate electrode extending from the gate line by a predetermined length along a second direction perpendicular to the first direction; a data line arranged on the first transparent substrate along a second direction perpendicular to the first direction, the gate line and the data line perpendicularly crossing each other and defining a pixel region; a thin film transistor arranged on the first transparent substrate and adjacent to the pixel region, the thin film transistor electrically connected to both the gate line and the data line; a common line arranged on the first transparent substrate along the first direction parallel with and adjacent to the gate line, the common line having a protrusion extending toward the gate line along the second direction spaced apart from the gate line by a predetermined distance; a first capacitor electrode overlapping a portion of the common line and the protrusion of the common line to form a first storage capacitor, the first capacitor electrode connected to the thin film transistor; a pixel electrode formed within the pixel region, the pixel electrode contacting the first capacitor electrode; a black matrix on the second transparent substrate, the black matrix covering the thin film transistor, the protrusion of the common line, and portions of the gate line and common line; and a common electrode on the second transparent substrate to cover the black matrix, wherein the predetermined length of the gate electrode is greater than the predetermined distance between the protrusion and the gate line.
