Publication number: 20160041432Abstract: In the step of curing a resin for bonding a TFT substrate and a counter substrate each having an alignment film that has been optically aligned by using UV-light, damage to the alignment film due to the UV-light can be prevented without using a light shielding mask. A UV-light absorption layer is formed between each black matrix on the counter substrate. The TFT and counter substrates are sealed at their periphery by a resin that is cured by UV-light radiated from the counter substrate side. Since the absorption layer has a high absorbability to UV-light at a wavelength of 300 nm or less that degrades the alignment film, damage to the alignment film due to the UV-light for curing the resin can be prevented. Thus, provision of a light shielding mask for shielding the UV-light for the display region can be saved.Type: ApplicationFiled: October 26, 2015Publication date: February 11, 2016Applicant: JAPAN DISPLAY INC.Inventors: Noboru KUNIMATSU, Yuko MATSUMOTO, Yasushi TOMIOKA, Masateru MORIMOTO, Atsuhiro KATAYAMA
