A liquid crystal display panel includes a base substrate, a first step difference compensating pattern, a gate metal pattern, a semiconductor pattern, a source electrode, a drain electrode, a pixel electrode and a color filter. The first step difference compensating pattern is disposed on the base substrate and includes an inorganic material. The gate metal pattern is disposed on the first step difference compensating pattern and includes a gate electrode and a gate line electrically connected to the gate electrode. The semiconductor pattern is overlapped with the gate electrode. The source electrode is electrically connected to the semiconductor pattern. The drain electrode is electrically connected to the semiconductor pattern and is spaced apart from the source electrode. The pixel electrode is electrically connected to the drain electrode. The color filter is overlapped with the pixel electrode.
