Lens panel, method for manufacturing lens panel, and display apparatus having lens panel

摘要

A lens panel includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate includes a first base substrate, a first electrode disposed on the first base substrate, and a first alignment layer disposed on the first electrode. The first alignment layer includes a unit lens area. The unit lens area includes a first alignment area having a first azimuthal angle and a second alignment area having a second azimuthal angle. The lens panel may be controlled to function as a Fresnel lens by adjusting the azimuthal angle of the alignment layer without electrodes having micro pitch patterns.

1. A lens panel comprising:
a first substrate comprising a first base substrate, first electrodes disposed on the first base substrate and spaced apart from each other along a first direction, and a first alignment layer disposed on the first electrodes, the first alignment layer comprising a unit lens area, the unit lens area comprising a plurality of first alignment areas having a first alignment direction and a plurality of second alignment areas having a second alignment direction different from the first alignment direction; a second substrate comprising a second base substrate, a second electrode disposed on the second base substrate, and a second alignment layer disposed on the second electrode and having a third alignment direction; and a liquid crystal layer disposed between the first substrate and the second substrate, wherein: the first and second alignment areas are alternately disposed with each other in the unit lens area along the first direction such that at least a boundary between the first alignment area and the second alignment area corresponds to a gap between adjacent first electrodes; and the third alignment direction crosses the first and second alignment directions.
