The present application provides: a pressure-sensitive adhesive which appropriately maintains a cell gap, facilitates implementation as a flexible element due to excellent adhesive force between an upper substrate and a lower substrate, and has excellent adhesion between the upper substrate and the lower substrate; and can provide a liquid crystal cell having excellent electro-optical characteristics and appearance uniformity by minimizing defects such as pressing or pushing of a pressure-sensitive adhesive. Such a liquid crystal cell can be applied to various light modulation devices such as sunroofs, eyewear, smart windows, window protection films, flexible display elements, active retarders for displaying 3D images, or viewing angle control films. 本申请提供了压敏粘合剂和包含所述压敏粘合剂的液晶单元，所述压敏粘合剂适当地保持单元间隙，由于上基底与下基底之间的优异粘合力而有利于实现为柔性元件，并且能够通过使诸如压敏粘合剂的挤压或推挤的缺陷最小化来提供具有优异的电光特性和外观均匀性的液晶单元。这样的液晶单元可以应用于各种光调制装置例如天窗、眼部佩戴物、智能窗、窗保护膜、柔性显示元件、用于显示3D图像的主动延迟器或视角控制膜。
