Abstract
A liquid crystal display includes: a liquid crystal capacitor; a first switching element which transmits a data voltage to the liquid crystal capacitor; a second switching element connected to the liquid crystal capacitor; and a transformation capacitor connected to the second switching element. A difference between a first time when the first switching element is turned on and a second time when the second switching element starts is turned on is greater than 1 horizontal period and less than 1 frame period.
Claims16
A liquid crystal display comprising:
- a first gate line which extends along a first direction and transmits a first gate signal;
- a second gate line which extends along the first direction and transmits a second gate signal;
- a data line which extends along a second direction perpendicular to the first direction and transmits a data signal;
- a storage electrode line which includes a portion extending along the first direction and transmits a predetermined voltage;
- a first thin film transistor comprising:
- a first control electrode connected to the first gate line;
- a first source electrode connected to the data line;
- and
- a first drain electrode including an end portion at one end opposite the first source electrode and a first portion at another end;
- a second thin film transistor comprising:
- a second source electrode which is disposed between the end portion and the first portion of the first drain electrode and is included in the first drain electrode;
- a second control electrode connected to the second gate line;
- a second drain electrode including a second portion overlapping the storage electrode line in a plan view;
- and
- the second source electrode disposed opposite the second drain electrode;
- and
- a pixel electrode which is physically and electrically connected to the first drain electrode and receives the data signal from the first drain electrode,
- wherein the second gate line is disposed between the first gate line and the storage electrode line in the plan view.
