Abstract

Provided is a liquid crystal display device including: a pair of transparent substrates including a liquid crystal layer interposed therebetween, wherein, at the liquid crystal layer side of one of the pair of transparent substrates, a plurality of scan lines and a plurality of signal lines are arranged in a display area in a matrix, first electrodes are formed in pixel areas partitioned by the scan lines and the signal lines, a second electrode is formed on the first electrodes with an insulating film interposed therebetween over at least the display area, a common line is formed outside the display area, and the second electrode is electrically connected to the common line via a low-resistance line which is formed along at least one side of the display area.

Claims (19)

1. A liquid crystal display device comprising:

a pair of transparent substrates including a liquid crystal layer interposed therebetween,

wherein, at the liquid crystal layer side of one of the pair of transparent substrates,

a plurality of scan lines and a plurality of signal lines are arranged in a display area in a matrix,

first electrodes are formed in pixel areas partitioned by the scan lines and the signal lines,

a second electrode is formed on the first electrodes with an insulating film interposed therebetween over at least the display area,

a common line is formed outside the display area, and

the second electrode is electrically connected to the common line via a low-resistance line which is formed along at least one side of the display area.

2. The liquid crystal display device according to claim 1 , wherein the low-resistance line is formed between the display area and the common line in plan view.

3. The liquid crystal display device according to claim 1 , wherein the low-resistance line is formed so as to overlap with the second electrode which extends to the outside of the display area in plan view.

4. The liquid crystal display device according to claim 1 , wherein the both ends of the low-resistance line are electrically connected to the common line.

5. The liquid crystal display device according to claim 1 , wherein:

the common line is positioned at a position separated from the display area in parallel, and

the low-resistance line and the common line are electrically connected via a connection line.

6. The liquid crystal display device according to claim 5 , wherein the low-resistance line and the connection line are formed of the same material as the scan lines or the signal lines.

7. The liquid crystal display device according to claim 1 , wherein:

the display area has a rectangular shape, and

the low-resistance line is formed in a longitudinal direction of the display area.

8. An electronic apparatus comprising the liquid crystal display device according to claim 1 .
