Liquid crystal display (LCD) panel, LCD and manufacturing method of LCD

The invention relates to a liquid crystal display (LCD) panel, an LCD and a manufacturing method of the LCD. The LCD panel comprises a first substrate and a second substrate which are arranged oppositely, a first light gap and a second light gap are arranged on one side of the first substrate, facing to the second substrate, a non-metal gasket is arranged on one side of the second substrate, facing to one side of the first substrate, and the non-metal gasket and the second light gap correspond to each other in position. The manufacturing method comprises the steps of: providing the first substrate, and forming the first light gap and the second light gap on the first substrate; and providing the second substrate, forming a grid electrode, a gate insulating layer, an active layer, a source electrode/drain electrode metal layer and a passivating layer on the second substrate in sequence, and forming the non-metal gasket at the second light gap correspondingly, wherein the non-metal gasket is formed by one or more of materials forming the gate insulating layer, the active layer and the passivating layer. The aperture opening ratio of the LCD panel is improved.
