Abstract

A liquid crystal display screen is provided. The liquid crystal display screen includes a capacitance type touch panel, an upper board, a liquid crystal layer, and a lower board. The capacitance type touch panel includes a substrate and a transparent conductive layer located on the substrate. The upper board includes an upper substrate, an upper electrode, and an upper alignment layer. The transparent conductive layer is configured to be an upper optical polarizer. The transparent conductive layer is a carbon nanotube layer having an anisotropic conductivity. The upper substrate is the substrate of the capacitance type touch panel.
