Liquid crystal displays, low-reflection polarizers with high uniformity and smoothness, and manufacture thereof

Liquid crystal displays, low-reflection polarizers with high uniformity and smoothness, and manufacture thereof. Murakami, Takashi (Konica Minolta Opto Inc., Japan). Jpn. Kokai Tokkyo Koho JP 2005043401 A2 17 Feb 2005, 104 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: G02B005-30. ICS: G02F001-1335; G02F001-1336. APPLICATION: JP 2003-199709 22 Jul 2003. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 38, 73 The polarizers have 1.4-4 m-width transparent supports on both sides, one of which is antireflective film (A) and the other is cellulose ester film (B). In prepn. of A, phosphate solns. of cellulose esters with total acyl substitution degree 2.7-2.9, Mn 80,000-200,000, and Mw/Mn 1.4-3.0, plasticizers other than phosphates, and UV absorbers are cast and biaxially oriented to give cellulose acylate films, whereon actinic ray-curable resin layers and antireflective layers are formed. In prepn. of B, cellulose ester solns. with total acyl substitution degree 2.6-2.9, Mn 80,000-200,000, and Mw/Mn 1. There are some commonly used reagents like 6079-76-1 in this article.4-3.0 are cast and drawn to show retardation Ro 20-320 nm or Rt 100-400 nm [Ro = (nx - ny) ′ d; Rt = [(nx + ny)/2 - nz] ′ d; nx, ny, nz = refractive index in in-plane slow axis direction, in-plane fast axis direction, and thickness direction, resp.]. The film B may contain rod-like compds. or discotic compds. and have actinic ray-curable layers. .

DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 38, 73 The cellulose ester films are manufd. by (1) casting solns. contg. plasticizers, UV absorbers, cellulose esters with total acylation 2.6-2.9, Mn 80,000-200,000 and Mw/Mn 1.4-3.0, CH2Cl2 as good solvents, good solvents having higher b.p. than that of CH2Cl2, and poor solvents, (2) stretching biaxially, and (3) drying at 3120°. The antireflective films are obtained by forming radiation-curable polymer layers on the cellulose ester films and laminating antireflective layers on the resulting optical films. Displays using the antireflective films or polarizing sheets contg. the antireflective films are also claimed. The cellulose ester films show low haze and good surface smoothness and give black band-free optical films. .
