Document Type and Number:
WIPO Patent Application WO/2020/252890
Kind Code:
A1
Abstract:
A display device (100) capable of switching to and back from an anti-peeping mode. A third substrate (130) is provided between a first substrate (110) and a second substrate (120). A pixel (140) is provided between the first substrate (110) and the third substrate (130). An interference pixel (150) is provided beside the pixel (140). A light control layer (160) is provided between the pixel (140) and the third substrate (130). An upper optical switch electrode (170) is provided at the second substrate (120). A lower optical switch electrode (180) is provided at the third substrate (130). An electrically-controlled optical switch layer (190) is provided between the second substrate (120) and the third substrate (130). A projection of the interference pixel (150) on the first substrate (110) overlaps with a projection of the lower optical switch electrode (180) on the first substrate (110).
