Liquid crystal display panel and manufacturing method thereof
View Patent ↗A liquid crystal display (LCD) panel and manufacturing method thereof capable of ensuring an aperture ratio while reducing the number of data lines by a change of an arrangement structure of subpixels includes a plurality of subpixels constituting a display region, a plurality of thin film transistors (TFTs) connected respectively to the plurality of subpixels, a plurality of gate lines connected to the TFTs and formed along long sides of the subpixels, a plurality of data lines connected to the TFTs and formed along short sides of the subpixels, a plurality of storage lines formed to pass through the subpixels along the short sides of the subpixels, a first common storage line connected commonly to one end of each of the plurality of storage lines, and a second common storage line connected commonly to an opposite end of each of the plurality of storage lines.
1. A liquid crystal display (LCD) panel, comprising:
a plurality of subpixels constituting a display region;
a plurality of thin film transistors (TFTs) connected respectively to the plurality of subpixels;
a plurality of gate lines connected to the TFTs and formed along long sides of the subpixels;
a plurality of data lines connected to the TFTs and formed along short sides of the subpixels;
a plurality of storage lines formed to pass through the subpixels along the short sides of the subpixels;
a first common storage line connected commonly to one end of each of the plurality of storage lines; and
a second common storage line connected commonly to the opposite other end of each of the plurality of storage lines.
2. The LCD panel as claimed in claim 1 , wherein the plurality of subpixels includes red, green and blue subpixels, and the red, green and blue subpixels are alternately repeatedly arrayed along the data lines.
3. The LCD panel as claimed in claim 2 , wherein the first and second common storage lines are formed of a first metal layer which is the same as the gate lines, and the storage lines are formed of a second metal layer which is the same as the data lines.
4. The LCD panel as claimed in claim 3 , further comprising:
a plurality of first contact electrodes for connecting the first common storage line to the plurality of storage lines; and
a plurality of second contact electrodes for connecting the second common storage line to the plurality of storage lines.
5. The LCD panel as claimed in claim 4 , wherein each of the first and second contact electrodes is formed of a third conductive layer for connecting the common storage lines to the storage lines through contact holes exposing the common storage lines and the storage lines.
6. The LCD panel as claimed in claim 3 , wherein the first common storage line is connected to an upper part of the plurality of storage lines via an upper non-display region of a non-display region encompassing the display region, and the second common storage line is connected to a lower part of the plurality of storage lines via a lower non-display region.
7. The LCD panel as claimed in claim 6 , wherein the second common storage line extends to the upper non-display region along right and left non-display regions in the lower non-display region.
8. The LCD panel as clamed in claim 7 , further comprising:
a first common pad connected to opposing ends of the first common storage line; and
a second common pad connected to opposing ends of the second common storage line.
9. The LCD panel as claimed in claim 8 , further comprising gate drivers disposed at the right and left non-display regions, for separately driving the plurality of gate lines.
10. The LCD panel as claimed in claim 9 , wherein the second common storage line passes by an outbound side of the gate drivers.
11. The LCD panel as claimed in claim 7 , further comprising a common pad connected commonly to opposing ends of each of the first and second common storage lines.
