DISPLAY PANEL SUBSTRATE AND SUBSTRATE EXPOSURE METHOD

摘要

The present invention provides a display panel substrate and substrate exposure method whereby exposure can be performed accurately by preventing misrecognition or failure of detection of a pattern. A display panel substrate according to the present invention has a display region in which are arranged a plurality of picture elements and is provided with a pattern extending along the direction of arrangement of the picture elements in this display region. This pattern includes a main section having a fixed width and other portions, and has corners in positions within ±5 µm from a line parallel with the two edges of this main section. Alternatively, this main section has a length of at least 20% but less than 100% with respect to the length of the picture elements.
