Problems solved by technology

However, the photosensitive resin composition currently used as a color photoresist cannot form a via hole with a gentle slope angle after coating, exposure, and development, so that the ITO is not well attached to the inner surface of the via hole.

Abstract

The invention relates to photosensitive resin.The photosensitive resin is prepared from, by mass, 20-30 parts of epoxy-acrylic resin, 20-30 parts of maleic anhydride, 1-6 parts of catalyst N,N-dimethylethanolamine, 10-20 parts of a photopolymerization initiator, 4-8 parts of water dispersion latex, 1-5 parts of rubber, 4-10 parts of inorganic additives with surfaces modified by organosilane and 60-80 parts of a solvent.The water development speed of the resin can be increased through the water dispersion latex, and meanwhile the image reproducibility is improved; due to the photopolymerization initiator, a liquid crystal display screen manufactured by adopting the resin has the high-quality imaging; in addition, the preparation method of the photosensitive resin is simple and controllable in technological process, short in production period, capable of sufficiently utilizing heat generated by a chemical reaction in the resin synthetizing process, capable of saving energy sources and free of three wastes.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, that is, to a liquid crystal display color filter; in particular to a photosensitive resin field. Background technique [0002] A thin film transistor liquid crystal display (TFT-LCD) is configured such that a glass substrate with a TFT array and a glass substrate with a color filter are stacked at a predetermined pitch, and liquid crystals are injected between the two glass substrates to form a panel, and the panel is applied electrical signal to provide a display. [0003] According to the light source of the backlight, the above-mentioned LCD can be classified into reflective type, transmissive type and transflective type. Reflective LCDs reflect an external light source and use it as a backlight, requiring a pre-installed reflector, while transmissive LCDs use an internal light source as their backlight, ie, the backlight unit's own light. [0004] Transflective LCDs are in the form...
