Problems solved by technology

However, there is still a disadvantage that the fluorescence efficiency of the light conversion part is low.
[0010] Korean Laid-Open Patent No. 10-2010-0056437 discloses a method of manufacturing a color conversion filter using an inkjet method in which a color conversion layer can be formed at a desired position without additionally forming partition walls. Low self-fluorescence efficiency of dyes and insolubility in common solvents due to the use of organic EL materials

Synthetic example 1

[0145] The porphyrazine compound represented by Chemical Formula 1-1 was synthesized as follows by a method known in literature (J. Am. Soc., 4839 (1952)).

[0146]

[0147] 50 parts by weight of metal-free octaphenylporphyrazine and 1.5 parts by weight of aluminum oxide were refluxed for 1.5 hours in a solvent of 25 parts by weight of o-dichlorobenzene. When the reaction was completed, the above reaction mixture was refluxed in a hot state. After the reaction, it was cooled to room temperature and the generated solid was washed with hot water and ethanol, and then extracted with chlorobenzene. Next, the above extract was crystallized to obtain pure aluminum octaphenylporphyrazine.

Synthetic example 2

[0149] Pure silicon octaphenylporphyrazine represented by Chemical Formula 1-2 was obtained in the same manner as in Synthesis Example 1 above except that silicic acid was used instead of alumina.

[0150]

Synthetic example 1

[0152] Pure manganese octaphenylporphyrazine represented by Chemical Formula 1-3 was obtained in the same manner as in Synthesis Example 1 above except that manganese anhydride was used instead of alumina.

Abstract

The present invention provides a self emission type photosensitive resin composition and a color conversion layer as well as a display device produced by the self emission type photosensitive resin composition. The above self emission type photosensitive resin composition is characterized by comprising a dye and a tetraazaporphyrin compound having aluminum (Al) or silicon (Si) as central metal. The self emission type photosensitive resin composition of the present invention has an effect of ensuring excellent optical density, fluorescence efficiency and luminous intensity characteristics.

Description

technical field [0001] The present invention relates to a self-luminous photosensitive resin composition, a color conversion layer manufactured using the self-luminous photosensitive resin composition, and a display device. Background technique [0002] In recent years, the display industry is shifting from cathode ray tube (cathode-ray tube, CRT) to plasma display panel (plasma display panel, PDP), organic light-emitting diode (organic light-emitting diode, OLED), liquid crystal display (liquid- Crystal display (LCD) and other flat-panel displays are undergoing rapid changes. Among them, LCD is widely used as a display device used in almost all industries, and its application range is continuously expanding. [0003] The LCD adjusts the transmittance while passing the white light generated by the backlight unit through the liquid crystal unit, and mixes the three primary colors that pass through the color filters of red (Red), green (Green), and blue (Blue) to realize full...
