US Patent 7532269 Liquid crystal displays

An LCD having an enhanced light transmittance and improved lateral visibility includes gate and storage electrode lines formed on a first insulating substrate, a data line insulated from and crossing the gate line, a first source electrode partially overlapping an nth gate line and connected to the data line, first and second drain electrodes partially overlapping the nth gate line and separated from the first source electrode, a first sub-pixel electrode electrically connected to a first drain electrode, a second sub-pixel electrode electrically connected to a second drain electrode, a second source electrode partially overlapping an (n+1)th gate line and electrically connected to the second sub-pixel electrode, and a third drain electrode partially overlapping the (n+1)th gate line and separated from the second source electrode and operable to boost a charge voltage of the first sub-pixel electrode and to drop a charge voltage of the second sub-pixel electrode.
