Abstract

The invention provides a photosensitive resin composition for forming spacers and an image display device. The photosensitive resin composition includes an alkali-soluble resin, a photopolymerization initiator and an ethylenically unsaturated compound, wherein the photopolymerization initiator includes an initiator having a structure represented by formula (I). The special structure of the above-mentioned photoinitiator makes the photosensitive resin composition containing it have good weather resistance, chemical resistance and good photoinitiation activity, and the amount of the initiator is small, and it is compatible with alkali-soluble resins and olefins. Saturated compounds have good compatibility, and more importantly, the photosensitive resin composition containing the above-mentioned components also has excellent elastic recovery rate, little pollution to liquid crystal molecules and good curing effect.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a photosensitive resin composition for forming spacers and an image display device. Background technique [0002] Liquid crystal display (LCD) utilizes the properties of switching the arrangement of liquid crystal molecules under the on / off effect of the voltage applied to the liquid crystal. For LCDs manufactured using photosensitive compositions, due to the influence of the electrical properties of the photosensitive composition itself and the impurities contained in the photosensitive composition, the voltage applied to the liquid crystal cannot be maintained. , There are cases where problems such as display unevenness of the display are caused by this. In particular, columnar spacers and photo spacers are used in liquid crystals for members close to the liquid crystal layer in color liquid crystal displays in order to keep the distance between two substrates constant. ...
