Abstract: An LCD panel being driven in an overlapping drive mode by applying a gate high voltage during n horizontal synchronous intervals is disclosed. The LCD panel includes: a plurality of gate lines; and a gate driver configured to include a plurality of stages connected to the plurality of gate lines. The plurality of stages are grouped in a plurality of stage groups each including n stages. Odd-numbered stage groups each allows the n stages to be arranged in a Z shape with having a display area therebetween. Even-number stage groups each allows the n states to be arranged in an inverse-Z shape with having the display area therebetween.

Abstract: A method of fabricating a display panel including a display region having a first pixel region where pixels are disposed, and a sensing region having a second pixel region where pixel groups are disposed and a light transmitting part disposed between the pixel groups, is discussed. The method can include forming a light shield layer at least in the sensing region, wherein the light shield layer includes an opening hole corresponding to the light transmitting part and exposes the light transmitting part to a laser beam through the opening hole. The method can further include forming a metal layer spaced apart from the light blocking layer in the first pixel region of the display region and the sensing region, and irradiating the laser beam to at least the sensing region to remove the metal layer from the light transmitting part.
