Liquid crystal display device including switching element with floating terminal

摘要

A liquid crystal display device includes: a first substrate for which a single pixel includes: first, second and third thin film transistors on the first substrate; a pixel electrode including a first subpixel electrode and a second subpixel electrode which are connected to the first thin film transistor and the second thin film transistor, respectively; and a divided reference voltage line connected to the third thin film transistor; a second substrate facing the first substrate; a common electrode on the second substrate; and a liquid crystal layer between the pixel electrode and the common electrode and including liquid crystal molecules. The third thin film transistor includes an electrically floating gate electrode, a source electrode defined by an extended portion of a terminal of the second thin film transistor, and a drain electrode defined by an extended portion of the divided reference voltage line.
