A display panel includes a first substrate and a spaced apart second substrate and a protection or other additional film attached to an outer and laterally extending major surface of the first substrate. The first substrate includes a first base substrate having a major lateral surface subdivided into a display region and a peripheral region, a color filter member disposing on the first base substrate and having a plurality of color filters, a light blocking member disposing on the peripheral region of the first base substrate and an overcoating member disposing on the color filter member and on the light blocking member and extending to cover a sidewall surface of the light blocking member. The extend overcoating member helps block charged particles from reaching the light blocking member, thus preventing discoloration of the color filter due to influx of static electricity associated with the charged particles.
