Abstract
A manufacturing method of a liquid crystal display panel includes vertically irradiating a first substrate and a second substrate with ultraviolet light for alignment. An energy compensation device is formed and/or placed in an irradiation direction of the ultraviolet light. An angle difference of pretilt angles between liquid crystal molecules inside the first substrate and liquid crystal molecules inside the second substrate is greater than a preset angle. An energy intensity inside the first substrate or inside the second substrate is controlled by the energy compensation device, so that pretilt angle difference between the liquid crystal molecules inside the first substrate and the liquid crystal molecules inside the second substrate is large.
