Abstract
A liquid crystal display screen includes a resistance-type touch panel and a liquid crystal display panel. The touch panel includes a first electrode plate and a second electrode plate opposite to the first electrode plate. The first electrode plate includes a first substrate and a first transparent conductive layer located on the first substrate. The second electrode plate includes a common substrate and a second transparent conductive layer. The liquid crystal display panel includes an upper optical polarizer, an upper substrate, an upper electrode, an upper alignment layer, a liquid crystal layer, a lower alignment layer, a thin film transistor panel, and a lower optical polarizer, from top to bottom in sequence. The upper substrate is the same with the common substrate. The upper optical polarizer is sandwiched between the second transparent conductive layer and the common substrate.
