Abstract
The present invention provides a liquid crystal display panel. The liquid crystal display panel includes drive circuits, data lines for transmitting the data signals, scan lines, and pixel units. Each of the drive circuits includes a level shifter and an output buffer. Voltage signals which are inputted to a non-inverting input terminal and an inverting input terminal of the level shifter are determined according to a number of inverting amplifiers of the output buffer. The present invention further provides a liquid crystal display device. The present invention can effectively decrease the manufacture cost of the liquid crystal display panel.
