Liquid crystal display device
View Patent ↗A liquid crystal display device mainly includes a first substrate, a second substrate, and a liquid crystal layer sandwiched between the first and the second substrates. The first substrate is attached to the second substrate by a radiation-cured sealant. The first substrate is provided with a light-shielding frame around the display area, wherein the frame forms the corners into a nonrectangular shape and superposes over a substantial portion of the sealant.
