Abstract
A touch-sensing liquid crystal panel and a fabrication method thereof are provided. The touch-sensing liquid crystal panel includes a color filter substrate and a transistor substrate. In the fabrication method, at first, a first glass substrate is provided. Thereafter, a sensing matrix is formed on a first surface of the first glass substrate at a baking temperature. The sensing matrix is formed from indium tin oxide (ITO), and a sheet resistance of the sensing matrix is equal to or less than 30 ohm/square. Then, color filters and a common electrode are disposed on a second surface of the first glass substrate to form a color filter substrate, wherein the second surface is opposite to the first surface. Thereafter, the transistor substrate is provided and combined with the color filter substrate. Thereafter, a slimming process is performed to slim a second glass substrate of the transistor substrate.
