Patent ID: 7733019

Claim:
A flat panel display device, comprising: a plurality of self-luminant devices, each comprising a light emitting layer; a lens sheet comprising a plurality of condensing lenses that correspond to the self-luminant devices, the lens sheet adapted to direct light emitted from the self-luminant devices to travel in a predetermined direction, a distance between the light emitting layer and an exterior portion of a corresponding condensing lens in a direction of propagation of the light is set so as not to overlap images of neighboring sub-pixels that are expanded by the condensing lenses; a first substrate having the self-luminant devices arranged thereon; and a sealing substrate adapted to seal the self-luminant devices, the lens sheet being arranged between either the self-luminant devices and the first substrate or between the self-luminant devices and the sealing substrate, with the condensing lenses being arranged within either the first substrate or the sealing substrate, the condensing lenses being convex and mating with corresponding concave surfaces on the sealing substrate.
