A display panel includes a substrate, a pixel array, and a plurality of shift registers. The pixel array is disposed on the substrate. The shift registers are disposed on the substrate for sequentially outputting a plurality of scanning signals to drive the pixel array. Each of the shift registers includes a pull-up transistor and a first reserve transistor. The pull-up transistor raises the voltage level of the corresponding scanning signal. A control terminal of the first reserve transistor is coupled to a control terminal of the pull-up transistor, and a second terminal of the first reserve transistor is coupled to a second terminal of the pull-up transistor. When the pull-up transistor in each of the shift registers has insufficient output ability, a first terminal of the first reserve transistor is coupled to a first terminal of the pull-up transistor.

A thin-film transistor photosensor and a liquid crystal display (LCD) panel respectively utilize a dielectric layer having F&#x2014;SiOC: H compound and a bump structure having F&#x2014;SiOC: H compound so as to form a thin-film transistor photosensor having lower resistor-capacitor loading (RC loading) and an LCD panel having low-dielectric F&#x2014;SiOC: H compound respectively. In addition, a method of forming a dielectric layer having F&#x2014;SiOC: H compound utilizes gases including trimethyl silane, carbon tetrafluoride, argon, and oxygen for thin-film deposition process so as to form a low-k F&#x2014;SiOC: H compound dielectric layer.
