Abstract: An optical sensor for detecting a peripheral light and a liquid crystal display device using the same are provided to supply sufficient current supply from the optical sensor without an additional amplification circuit because the first transistors are parallel arranged. A sensor(202) comprises two or more first transistors(M11-M1n) parallel connected between an output line(L2) and a base power source(VSS). An external light sensing signal is outputted through the output line. The first electrode of the first transistors is connected to the base power source. The second electrode is connected to the output line of an optical sensor. The gate electrode of the first transistors is connected to the first electrode and the base power source. The first transistors are parallel connected. Respective first transistors are connected in a reverse diode connection type. Here, the gate electrode of the first transistors is located in an opening of a black matrix(30) in order to receive external light. A compensation unit(200) comprises the second transistors(M21-M2n) connected between the first transistors and the second voltage source(Vp).

Abstract: A liquid crystal display is provided to reduce capacitance between a common electrode and a data electrode. A gate line(8) is formed on a lower substrate. A data line(6) is formed in a direction crossed with the gate line at an interval of a first insulating film with the gate line. Pixel electrodes(4) are formed in every pixel area of a crossing unit between the gate line and the data line. A common electrode(2) is formed to cover the pixel areas at an interval of a second insulating film with the pixel electrodes. Holes(3,40) are positioned in overlapped parts between the common electrode and the data line, and are formed on the common electrode to expose the second insulating film.
