Abstract
A method for manufacturing a display screen, including: preparing a first substrate and reserving at least one first hole region on the first substrate; preparing a second substrate and reserving at least one second hole region on the second substrate; adding liquid crystals onto the first substrate or the second substrate and aligning the first substrate with the second substrate such that the first hole region is aligned with the second hole region; and forming a hole penetrating the first substrate and the second substrate through the first hole region and the second hole region. The liquid crystals do not occupy the first hole region and the second hole region.
