The present invention relates to a thin film transistor array panel, a liquid crystal display, and a method capable of reducing an effect on neighboring pixels in a process of repairing a pixel defect. The thin film transistor array panel may include: a thin film transistor connected to a gate line and a data line to define a pixel area; a pixel electrode formed in the pixel area and connected to the thin film transistor; and a storage electrode including a first portion overlapping the data line between two adjacent gate lines. The storage electrode may also include a second portion connected to the first portion and enclosing an edge of the pixel area except for a region where the first portion is formed. The storage electrode may be branched between pixel electrodes respectively formed in two adjacent pixel areas.
