Abstract:
A display substrate includes gate lines, driving circuit part, signal lines, connection lines and a contact part. Gate lines are formed on a display area and intersect data lines. Driving circuit part is formed on a peripheral area surrounding the display area and provides a gate signal to the gate lines. Signal lines are formed adjacent to the driving circuit part and provide a driving signal to the driving circuit part. Connection lines include a first end portion overlapped the signal lines and a second end portion electrically connected with the driving circuit part. A contact part is formed on the signal lines and connects the first end portion with the signal lines.
Abstract:
A gate driving circuit includes a shift resister having stages cascade-connected to one another. Each stage includes a pull-up part, a first pull-up driving part, a first pull-down part and a first ripple prevention part. The pull-up part outputs a high value of a first clock signal to a first output terminal. The first pull-up driving part applies a low value to a control electrode of the pull-up part to turn off the pull-up part. The first pull-down part applies the low value to the signal outputted to the first output terminal. The first ripple prevention part applies the low value of the first input signal to the control electrode of the pull-up part to turn off the pull-up part, and prevents ripple from occurring at the control electrode of the pull-up part. Thus, an abnormal gate-on signal is prevented, to reduce driving malfunction of a display apparatus.

An array substrate includes a base substrate, a dummy circuit section, a dummy pixel portion, an extended line, a common voltage line, and an overlap portion. Pixel portions are formed in a display area. The dummy circuit section is formed in a peripheral area to protect the pixel portions from static electricity.
