An array substrate for use in an in-plane switching liquid crystal display device
has a plurality of common electrodes and a plurality of pixel electrodes. One of
the common electrodes is formed at the same time with the plurality of pixel electrodes
using a transparent conductive material. This transparent common electrode is connected
to other common electrode through a common electrode connector. Therefore, aperture
ratio can be increased. Further in the present invention, a capacitor electrode
is disposed over the common line and then forms a first storage capacitor with
a portion of the common line, and a pixel electrode connector is disposed over
the gate line and then forms a second storage capacitor with a portion of the gate
line. As a result, the IPS-LCD device can obtain an improved and stable capacitance
from the two storage capacitors.
