Display panel, method of fabricating display panel, display device including display panel

A liquid crystal display panel, comprising:

• a light guide layer having a first refractive index,
• a refractive layer on the light guide layer,
• a first polarizing layer on the refractive layer,
• a color filter layer on the first polarizing layer,
• a liquid crystal layer on the color filter layer, and
• an array substrate on the liquid crystal layer,
• wherein the refractive layer comprises a plurality of higher refractive index portions having a second refractive index and a plurality of lower refractive index portions having a third refractive index, the plurality of higher refractive index portions and the plurality of lower refractive index portions being arranged in an alternating manner,
• wherein the second refractive index is larger than the first refractive index,
• wherein the third refractive index is smaller than the first refractive index, and
• wherein the liquid crystal display panel is configured to emit light substantially through the higher refractive index portions of the refractive layer.
