Abstract

A subpixel structure of a liquid crystal display is disclosed. The subpixel structure is disposed between a first substrate and a second substrate, in which the subpixel structure includes a first portion and a second portion. The subpixel structure further includes: a data line, a first scan line and a second scan line intersecting the data line; a first transistor disposed on the first scan line and connected to the first portion of the subpixel structure; a second transistor disposed on the first scan line and connected to the second portion of the subpixel structure; and a third transistor disposed on the second scan line and connected to the second portion of the subpixel structure.
