Patent ID: 8164726

Claim:
A display device comprising: a pair of substrates; at least a pair of electrodes interposed between the pair of substrates; a display element interposed between the pair of electrodes; and an antireflection film provided over an outer side of one of the pair of substrates, wherein one of the pair of substrates is a light-transmitting substrate, wherein the antireflection film comprises a plurality of pyramidal projections and a plurality of films, wherein the plurality of pyramidal projections are covered with the plurality of films, respectively, wherein a refractive index of the plurality of films is higher than a refractive index of the plurality of pyramidal projections, wherein an interval is provided at least between one side of a base included in one of the pyramidal projections and one side of a base included in an adjacent pyramidal projection, wherein a difference between the refractive index of the plurality of pyramidal projections and the refractive index of the plurality of films is greater than or equal to 0.05 and less than or equal to 0.65, and wherein a height difference between a top of the plurality of pyramidal projections and a top of the plurality of films is 100 nm or less.
