Abstract
An ultra-slim bezel display panel includes a plurality of light blocking walls formed on a peripheral area of a TFT substrate and a plurality of light blocking walls and a plurality grooves formed on a peripheral area of the CF substrate. The heights of the light blocking walls and the widths of the grooves are determined by taking an additional jet quantity resulting from precision error of a machine into consideration so that, through calculation, the laid sizes of the light blocking walls and the grooves can be correctly determined to prevent, during coating of Pl liquid on the TFT substrate and the CF substrate, the Pl liquid coated on an outer circumference of an active area from flowing backward into the active area. The light blocking walls that are provided on the TFT substrate and have different heights are formed through exposure with a half-tone mask.
