A liquid crystal display panel including a first substrate, a second substrate, scan lines, data lines, pixel unit sets, and a liquid crystal layer is provided. The scan lines, data lines, and pixel unit sets are disposed on the first substrate. A first gap is formed between two adjacent pixel unit sets. Each of the pixel unit sets includes pixel units, and a second main space is formed between two adjacent pixel units. Each of the pixel units includes an active device electrically connected to a scan line and a data line, and a transparent pixel electrode has slits and electrically connected to the active device. The width of the first gap is greater than that of the second gap.
