Abstract:
1. A display device comprising: a lighting device comprising a first substrate and a patterned light emitting element disposed on a surface of the first substrate and comprising a patterned electrode; a liquid crystal display device attached to the first substrate of the lighting device and comprising a second substrate, a plurality of reflective electrodes disposed on the second substrate, a liquid crystal layer disposed on the reflective electrodes, a common electrode disposed on the liquid crystal layer, and a third substrate disposed on the common electrode layer; and a polarizing plate and a light scattering layer that are disposed between the first and third substrates so that the first substrate, the polarizing plate, the light scattering layer and the third substrate are stacked in this order, wherein a first transparent layer is disposed between the surface of the first substrate on which the patterned light emitting element is disposed and the liquid crystal layer and has a first refractive index, a second transparent layer is disposed between the surface of the first substrate on which the patterned light emitting element is disposed and the liquid crystal layer, has a second refractive index and is in contact with the first transparent layer, and a ratio of the first and second refractive indices is between 1.22 and 0.82, the first transparent layer and the second transparent layer are stacked in a direction of the stacking of the first substrate, the polarizing plate, the light scattering layer and the third substrate and not stacked in a direction perpendicular to the direction of the stacking of the first substrate, the polarizing plate, the light scattering layer and the third substrate, the light scattering layer is in direct physical contact with the polarizing plate and the third substrate, the lighting device further comprises a light shield layer that covers and is wider than the patterned electrode, and a distance (L
