Claim Text:
1. A method for manufacturing a 3D display device, comprising steps of: A1, preparing a display unit, a polarization direction of the emitting light of the display unit being adjusted to be parallel to a ridge direction of a concave lens film of a birefringent grating to be formed later; A2, disposing a transparent substrate on a light emitting side surface of the display unit; A3, forming a transparent electrode on the transparent substrate disposed on the light emitting side surface of the display unit; B1, forming the concave lens film on the transparent electrode; C1, rubbing the concave lens film along the ridge direction of the concave lens film; D1, forming liquid crystal polymer on a light emitting side surface of the concave lens film to make the liquid crystal polymer being oriented by the concave lens film; E1, forming an alignment layer on another transparent substrate followed by orienting through rubbing, after which the another substrate formed with the alignment layer is directly assembled together with the concave lens film to form the birefringent grating, with liquid crystal polymer interposed therebetween; and F1, orienting and curing the liquid crystal polymer in the birefringent grating.
