Abstract
A display panel according to one aspect of the present invention includes a lower substrate, an upper substrate and a liquid crystal layer. The lower substrate includes a plate, a switching element, an insulating layer, a transmission electrode and a protrusion. The plate has a transmission region through which a light may pass. The switching element is formed on the plate. The insulating layer is formed on the plate to cover the switching element. The transmission electrode is electrically connected to the switching element. The transmission electrode is formed in the transmission region. The protrusion divides the transmission region into a plurality of transmission portions. The upper substrate faces the lower substrate. The liquid crystal layer is disposed between the lower substrate and the upper substrate. Advantageously, an image display quality of the display apparatus is improved, and manufacturing cost is decreased.
