| 20090122214 | DISPLAY PANEL AND METHOD OF MANUFACTURING A DISPLAY SUBSTRATE OF THE DISPLAY PANEL - A display panel includes n gate lines, a data line, a first pixel and a second pixel. The gate lines extend in a first direction. The data line extends in a second direction transverse to the first direction. The first pixel includes a first pixel electrode connected to one of the (n−1) gate lines to receive a data voltage through the data line. The second pixel includes a second pixel electrode and a light-blocking pattern. The second pixel electrode is connected to the (n)-th gate line to receive the data voltage through the data line. The light-blocking pattern obscures the second pixel to possibly reduce a luminance difference between the first and second pixels. | 05-14-2009 |
