A manufacturing method for a liquid crystal panel, comprising: coating a photoresist layer on a substrate; utilizing a first exposure energy and a first mask for executing a first exposure process to form a spacing column having a first height, wherein, the first mask has a first light transparent area corresponding to a dark area; utilizing a second exposure energy and a second mask for executing a second exposure process to form a spacing column having a second height, wherein, the second mask has a second light transparent area corresponding to the dark area, and the second height is greater than the first height; and removing an unexposed portion of the photoresist layer. Through above way, the present invention can improve the pixel transmittance of the dark area in order to reduce or eliminate the dark area.
