Abstract
An array substrate for a liquid crystal display panel is disclosed. The array substrate includes a first substrate, a Lower Temperature Polycrystal Silicon (LTPS) Thin-Film-Transistor (TFT) disposed on the first substrate, a color photoresist layer disposed on the LTPS TFT, and multiple photo spacers disposed above the color photoresist layer. A liquid crystal display panel including the array substrate and a second substrate disposed oppositely to the array substrate is also disclosed. The present invention utilizes the second substrate to be aligned with the LTPS TFT array substrate in order to form the liquid crystal display panel. Because the second substrate is a bare substrate (without a pattern), when the second substrate is aligned with the array substrate, the alignment precision is not under consideration. Accordingly, apertures ratios of the liquid crystal display panel do not have difference.
