摘要:
A touch-sensing liquid crystal display (LCD) panel including an active device array substrate, an opposite substrate, and a liquid crystal layer disposed therebetween is provided. The active device array substrate includes a first substrate, a pixel array, a plurality of touch-sensing pads, and an electric field shielding layer. The pixel array is disposed on the first substrate and includes a plurality of sub-pixels arranged in an array, a plurality of scan lines, and a plurality of data lines. The touch-sensing pads are disposed on the first substrate. The electric field shielding layer is disposed on the pixel array and arranged between sub-pixels adjacent to each other, and the electric field shielding layer includes a pattern. The opposite substrate includes a common electrode and a plurality of touch-sensing protrusions disposed above the touch-sensing pads. Therefore, when the touch-sensing LCD panel is pressed, press mura is substantially eliminated.
