Abstract

A display apparatus includes: a substrate having a display area and a peripheral area around the display area; a first voltage wiring on one side of the peripheral area; a plurality of first voltage lines arranged in a first direction at the display area, extending in a second direction, and electrically connected to the first voltage wiring; a plurality of second voltage lines arranged in the second direction at the display area and extending in the first direction; a plurality of first connectors connecting the plurality of first voltage lines to the plurality of second voltage lines; a plurality of first auxiliary patterns extending in the first direction or the second direction on the display area; and a plurality of second connectors connecting at least one of the plurality of first voltage lines or the plurality of second voltage lines to the plurality of first auxiliary patterns.

First claim

What is claimed is:

1 . A display apparatus comprising:
a substrate having a first display area, second display areas at both sides of the first display area in a first direction, and a peripheral area around the first and second display areas; a pad unit at the peripheral area and including a plurality of first pads and a plurality of second pads; a plurality of first data lines extending in a second direction on the first display area and respectively connected to the plurality of first pads; a plurality of second data lines extending in the second direction on the second display areas; a plurality of auxiliary row lines extending in the first direction on the first display area and the second display areas; and a plurality of auxiliary column lines extending in the second direction on the first display area and the second display areas, wherein first auxiliary column lines that are some of the plurality of auxiliary column lines include first column connection portions respectively connected to the plurality of second pads, first auxiliary row lines that are some of the plurality of auxiliary row lines include first row connection portions respectively connecting the first column connection portions of the first auxiliary column lines to the plurality of second data lines, a first driving voltage is applied to second auxiliary row lines that are some others of the plurality of auxiliary row lines, and a second driving voltage having a different level than the first driving voltage is applied to second auxiliary column lines that are some others of the plurality of auxiliary column lines.

2 . The display apparatus of claim 1 , wherein the first auxiliary column lines respectively include second column connection portions to which the first driving voltage is applied, and
the second column connection portions of the first auxiliary column lines are respectively spaced apart from the first column connection portions of the first auxiliary column lines.

3 . The display apparatus of claim 1 , wherein the first auxiliary row lines respectively include second row connection portions to which the first driving voltage is applied, and
the second row connection portions of the first auxiliary row lines are respectively spaced apart from the first row connection portions of the first auxiliary row lines.

4 . The display apparatus of claim 1 , wherein at least one of the second auxiliary row lines is between the first auxiliary row lines.

5 . The display apparatus of claim 1 , further comprising:
a first voltage wiring in the peripheral area and configured to transmit the first driving voltage; and a second voltage wiring in the peripheral area and configured to transmit the second driving voltage.
