Problems solved by technology
In naked-view three-dimensional liquid crystal displays, the alignment film must have sufficient alignment force to make the liquid crystal molecules align neatly and evenly after directional rubbing; if the alignment film has insufficient alignment force for liquid crystals, the liquid crystal molecules will The discontinuity of the alignment produces disclination lines, resulting in lower image quality of the displayed 3D images, which in turn causes adverse visual phenomena such as overlapping images or uneven colors when the user watches the 3D images through the 3D liquid crystal display.

An acrylic acid series resin composition comprises an acrylic ester component, a photoinitiator and a binder. The acrylic ester component includes first acrylic ester and second acrylic ester, wherein the first acrylic ester and the second acrylic ester are shown in a formula (I) and a formula (II): CH2=CR1COO(CHR2CH2O)n(CH2)mCH3 (I), CH2=CR3COO(CHR4CH2O)pAr (II). In the formula (I), R1 and R can be same or different and respectively represent hydrogen or methyl, n represents 1-3, and m represents 0-2. In the formula (II), R3 and R4 can be same or different and respectively represent hydrogen or methyl, Ar represents substituted or unsubstituted phenyl, and p represents 1-2. The invention also provides an alignment film which is formed in such a manner that the acrylic acid series resin composition mentioned above is coated and exposed. A three-dimensional liquid crystal display made of the alignment film is good in alignment force.
Description
technical field [0001] The present invention relates to an acrylic resin composition, in particular to an acrylic resin composition comprising a first acrylate and a second acrylate with specific functional groups. Background technique [0002] In liquid crystal displays, it is generally necessary to use an alignment film to arrange the liquid crystal molecules in a specific direction. In naked-view three-dimensional liquid crystal displays, the alignment film must have sufficient alignment force to make the liquid crystal molecules align neatly and evenly after directional rubbing; if the alignment film has insufficient alignment force for liquid crystals, the liquid crystal molecules will The discontinuity of the alignment produces disclination lines, resulting in lowered image quality of the displayed 3D images, which in turn causes adverse visual phenomena such as overlapping images or color unevenness when the user watches the 3D images through the 3D liquid crystal dis...
