1. A liquid crystal display panel, comprising:
a first substrate, having a plurality of scan lines, data lines and thin film transistors are disposed on the first substrate,
the thin film transistors being driven by the scan lines and the data lines, at least one of the scan lines and the data lines
having a plurality of patterned openings with a first necking portion, wherein each of the scan lines and each of the data
lines comprise:
a first conductive layer, having a first opening;
a second conductive layer, disposed on the first conductive layer, wherein the second conductive layer has a second opening,
and the second opening is smaller than the first opening; and
a third conductive layer, disposed on the second conductive layer, wherein the third conductive layer has a third opening,
the third opening is larger than the second opening, and each of the patterned openings comprises the first opening, the second
opening and the third opening;
a second substrate, disposed above the first substrate, wherein a plurality of photo spacers with a second necking portion
are disposed on the second substrate and the photo spacers with the second necking portion are wedged in the patterned openings
with the first necking portion; and
a liquid crystal layer, disposed between the first substrate and the second substrate.
