Abstract
An IPS-LCD panel includes first and second substrates, and a liquid crystal interposed therebetween. On the first substrate, gate and data lines are formed perpendicular to each other to define a pixel region. On the pixel region, pixel and common electrodes are formed perpendicular to the gate line, and transverse pixel and common lines are electrically connected with the pixel and common electrodes, respectively. Since a triangular groove is etched away around a cross point between the pixel electrode and the transverse pixel line, a uniform gap is achieved between the pixel and common electrodes. Due to the uniform gap, a uniform electric field is applied between the pixel and common electrode such that the liquid crystal molecules are aligned uniformly throughout the pixel region.
