Abstract
A display substrate includes a signal line, a thin-film transistor ('TFT'), a key pattern, a light-blocking pattern, a color filter, a pixel electrode and an alignment key. The signal line and the key pattern are formed on a substrate. The TFT is electrically connected to the signal line. The light-blocking pattern is formed on the substrate and covers the signal line, the TFT and the key pattern. The color filter is formed in a unit pixel area of the substrate. The pixel electrode is formed on the color filter and is electrically connected to the TFT. The alignment key is formed on the light-blocking pattern, and a position of the alignment key on the substrate corresponds to a position of the key pattern on the substrate.
