Abstract

A display substrate includes a gate line, a data line, a pixel electrode, a storage line, a dual transistor, a connection transistor, a voltage-decreasing electrode, a first contact electrode and a second contact electrode. The voltage-decreasing electrode is disposed on the storage line. The voltage-decreasing electrode is connected to a connection drain electrode of the connection transistor. The first contact electrode overlaps with the first pixel part and is electrically connected to the first pixel part. The first contact electrode is connected to a first drain electrode of the dual transistor and a connection source electrode of the connection transistor. The second contact electrode overlaps with the second pixel part and is electrically connected to the second pixel part. The second contact electrode is connected to a second drain electrode of the dual transistor. Therefore, the aperture ratio of the display device may be increased.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2008-0053048, filed on Jun. 5, 2008 in the Korean Intellectual Property Office (KIPO), the contents of which are herein incorporated by reference in their entirety.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]Exemplary embodiments of the present invention relate to a display substrate. More particularly, exemplary embodiments of the present invention relate to a display substrate, a method of manufacturing the display substrate, and a display device having the display substrate.[0004]2. Discussion of the Related Art[0005]Generally, a liquid crystal display (LCD) device includes a first substrate having pixel electrode formed in a unit pixel, a second substrate having common electrode opposite to the first substrate, and a liquid crystal layer interposed between the first and second substrates. An arrangement of liquid crystal molecules of...
