Abstract
The present disclosure relates to a color film substrate, a display panel and a method for detecting a display panel. The CF substrate includes a display region and a peripheral region corresponding to a dummy pixel region around the display region. A black matrix of the color filter substrate includes a light transmitting section in a portion of the peripheral region corresponding to a dummy pixel unit. The light transmitting section includes a first set of light transmitting sections and a second set of light transmitting sections. Each of the first and second set of light transmitting sections is respectively in a portion that extends along a first side and a second side which is opposite to the first side of the display region and corresponds to the dummy pixel unit.
