Abstract: A touch display device and a touchscreen panel. Even in the case in which touch electrodes have different sizes or shapes or a located in different positions, a difference in capacitance is not formed among the touch electrodes. High touch sensitivity can be obtained. The touch display device comprises a plurality of touch electrodes, wherein a first touch electrode of the plurality of touch electrodes occupies a first area and comprises first mesh-shaped electrode metal. The touch display device comprises first dummy metal in a same layer as the first mesh-shaped electrode metal and in the first area occupied by the first touch electrode, the first dummy metal being electrically disconnected from the first mesh-shaped electrode metal.

Abstract: A liquid crystal display is provided which can avoid degradation of picture quality by preventing deviations in parasitic capacitance between a data line and a pixel electrode. The liquid crystal display includes data lines and gate lines, compensation patterns covering the data lines, thin film transistors disposed at regions neighbored to crossings of the data and gate lines, pixel electrodes disposed in pixel regions defined by the crossings and respectively connected to the thin film transistors; and a common electrode disposed to overlap the pixel electrodes, One edge of each of the compensation patterns is spaced apart from the pixel electrodes by a predetermined distance.
