Description

technical field

[0001] The present application relates to light modulating elements and their use.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2018-0076481 filed on July 2, 2018 and Korean Patent Application No. 10-2019-0079555 filed on July 2, 2019, the disclosure of which Incorporated herein in its entirety by reference. Background technique

[0003] In Patent Document 1 (Korean Patent Laid-Open No. 1775332), a light modulation element such as a liquid crystal cell may generally include a spacer to maintain a cell gap between an upper substrate film and a lower substrate film. In addition, when the light modulation element is applied to a strap-on flexible display device such as eyewear, flexible substrate films may be required for the upper and lower substrate films.

[0004] However, when a flexible base film is applied to manufacture a light modulation element, there may arise a problem that, due to a difference i...
