Abstract

A thin film transistor array panel according to an embodiment of the present invention includes: a substrate; a gate line disposed on the substrate and extending in a first direction; a capacitive electrode separated from the gate line and elongated in a second direction; a data line intersecting the gate line; a thin film transistor connected to the gate line and the data line and including a drain electrode; a coupling electrode overlapping the capacitive electrode and connected to the drain electrode; and a pixel electrode including at least one first subpixel electrode connected to the drain electrode and a second subpixel electrode connected to the capacitive electrode and spaced apart from the at least first subpixel electrode by a gap that overlaps the capacitive electrode or the coupling electrode.

Claims (22)

1. A thin film transistor array panel comprising:

substrate;

a gate line disposed on the substrate and extending in a first direction;

a capacitive electrode separated from the gate line and elongated in a second direction;

a data line intersecting the gate line;

a thin film transistor connected to the gate line and the data line and including a drain electrode;

a coupling electrode overlapping the capacitive electrode and connected to the drain electrode; and

a pixel electrode including at least one first subpixel electrode connected to the drain electrode and a second subpixel electrode connected to the capacitive electrode and spaced apart from the at least one first subpixel electrode by a gap that overlaps the capacitive electrode or a coupling electrode.

2. A liquid crystal display comprising:

a gate line;

a data line intersecting the gate line;

a capacitive electrode separated from the gate line and elongated substantially parallel to the date line;
