Abstract
An in plane switching (IPS) mode liquid crystal display (LCD) panel is fabricated with a reduced number of mask processes and includes a thin film transistor (TFT) array substrate with a TFT provided at a crossing of gate and data lines, a protective film protecting the TFT, a pixel electrode connected to the TFT, a common line substantially parallel to the pixel electrode, a common electrode connected to the common line to generate a horizontal electric field with the pixel electrode, and a pad including a transparent conductive material and connected to the gate line, the data line and/or the common line. A color filter array substrate is joined to, and overlaps a portion of, the TFT array substrate. Portions of the protective film where the color filter array substrate which do not overlap the TFT array substrate are removed to expose the transparent conductive material included in the pad.
