Abstract
A plastic substrate includes: a plastic support member having light transmittance; and a first organic-inorganic hybrid layer on the plastic support member. The first organic-inorganic hybrid layer includes: a first organic-inorganic hybrid matrix; and ions implanted into the first organic-inorganic hybrid matrix at a side opposite to a side adjacent the plastic support member. An amount of the ions per unit area is in a range from about 2×1013/cm2 to about 2×1014/cm2.
