Problems solved by technology

[0018] Although in the case of a general photosensitive resin composition, a photoinitiator must be used for polymerization, but not only the free radicals generated by the photoinitiator will reduce the fluorescence efficiency of the phosphor, but will also New problems such as yellowing of the color conversion layer caused by the photoinitiator in the post-bake process implemented in the process

[0147] Production Example 1: Production of Alkaline Soluble Resin A

[0148] As a dropping funnel, 74.8 g (0.20 moles) of benzylmaleimide, 43.2 g (0.30 moles) of acrylic acid, 118.0 g (0.50 moles) of vinyltoluene, tert-butylperoxy-2-ethyl 4g of caproic acid ester, 40g of propylene glycol monomethyl ether acetate (PGMEA) were stirred and mixed for later use, and used as a chain transfer agent drip tank (chain transfer agent drip tank), after adding 6g of n-dodecyl mercaptan and 24g of PGMEA, the Stir to combine and set aside.

[0149] Thereafter, 395 g of PGMEA was introduced into the flask, and after changing the atmosphere in the flask from air to nitrogen, the temperature of the flask was raised to 90° C. while stirring. Next, dropping of the monomer and the chain transfer agent from the dropping funnel was started. The dripping liquid was kept at 90°C for 2 hours respectively, and after 1 hour, the temperature was raised to 110°C and maintained for 3 hours, then it was in...
