Abstract

In an array substrate and a method of manufacturing the array substrate, an array substrate includes a first switching element, a second switching element, a third switching element and a fourth switching element. The first switching element is electrically connected to a first data line. The second switching element is electrically connected to a second data line adjacent to the first data line. The third switching element is electrically connected to a data power line interposed between the first and second data lines. The fourth switching element is electrically connected to a gate power line receiving a voltage having different polarity from a voltage applied to the data power line. Therefore, light transmittance, opening ratio and display quality are improved.
