Patent attributes
The present invention provides a liquid crystal display device having a liquid crystal display portion, a gate driver circuit, a source driver circuit, and a power supply circuit, where the liquid crystal display portion includes unit pixels with pixel switching elements and pixel electrodes arranged in a matrix. The pixel switching elements are thin film transistors that are made of polycrystalline silicon semiconductor formed on an insulating substrate. The power supply circuit is a charge pump-type power supply circuit, is made of a polycrystalline silicon semiconductor, and is a built-in circuit integrally formed on an insulating substrate. With such a configuration, a liquid crystal display device that greatly reduces power consumption is realized.
