Embodiment

[0456] Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited to the following examples unless the gist of the present invention is exceeded. In addition, unless otherwise specified, "part" is a standard of quality.

[0457] Micronization (salt grinding) of pigment powders

[0458] Put 200 parts of diketopyrrolopyrrole red pigment C.I. Pigment Red 254, 1600 parts of sodium chloride, and 360 parts of diethylene glycol into a stainless steel 1-gallon kneader (manufactured by Inoue Seisakusho), and knead at 50°C 8 hours. Then, this kneaded product was poured into 10 liters of hot water, and while heating to 80° C., HCl was added to adjust the pH to 2.0. Then, it was stirred for 2 hours to make a slurry, and filtration and water washing were repeated to remove sodium chloride and diethylene glycol. Then, it dried at 60 degreeC overnight, and obtained 190 parts of red pigments. The average primary particle di...

Abstract

The present invention provides a curable composition for coloring pixel, color filter and liquid crystal display device. The present invention provides a curable composition for coloring pixel with good contrast and the like color characteristics and without bad actions of LCD at a low-cost and a LCD device. The present invention provides a curable composition for coloring pixel, wherein, the total amount of sodium atoms, sodium ions, potassium atoms and potassium ions in the range of 5 - 50ppm.

Description

technical field [0001] The present invention relates to a curable composition for colored pixels containing an organic pigment, and a color filter and a liquid crystal display device using the curable composition for colored pixels. Background technique [0002] Liquid crystal display devices commonly used in mobile phones, personal computers, televisions, and the like can perform color display by including color filters. By applying a voltage to the liquid crystal, the liquid crystal is aligned, and the backlight is transmitted or blocked according to the voltage applied to the liquid crystal. The transmitted light passes through the color filter to perform color display. [0003] If the liquid crystal is contaminated by ions or the like contained in the components constituting the liquid crystal cell, such as a color filter, the voltage applied to the liquid crystal becomes abnormal, the orientation of the liquid crystal cannot be expected, and a normal screen cannot be d...
