Description
The present invention relates to a colored resin composition for forming a front light-shielding layer of a display device.
Generally, in order to improve the visibility of the display, the reflectance is decreased in the front edge of a display device such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), an OLED (Organic Light Emitting Diode) and an AMOLED (Active Matrix Organic Light Emitting Diode) And a bezel which is a front shading layer of a display device that performs a function of shielding light such that the inside of the display is not visible is formed.
The bezel portion is formed by photolithography using a colored photosensitive composition or by roll printing. In addition, a vacuum deposition method is also used (Korean Patent Laid-Open No. 10-2011-0053940).
However, since photolithography is essentially a complicated process such as exposure and development, it has a disadvantage in that it is not only poor in productivity and consumes a large amount of material, and the roll printing method has a disadvantage that it is not easy to form a precise pattern.
On the other hand, the bezel portion needs to be formed in various colors in consideration of the design property of the display device, and in order to meet the optical density required in the case of bright colors, the bezel portion should be formed to a thickness of about 15 mu m to 25 mu m. However, in the conventional photolithography or roll printing method, a coating film having a thickness of 15 μm to 25 μm can not be formed by one application, which is disadvantageous in that it is necessary to repeat the process. Also, in the case of vacuum deposition, it takes a considerable time to form a coating film having a thickness of 15 to 25 占 퐉.
