Problems solved by technology

However, the conventional BM containing metal fine particles can obtain a black matrix with high optical density even though it is a thin film, but the reflectance of the produced BM is high, and when it is used in a color filter, there is a problem of color deviation
In particular, when the metal filling rate is increased in thinned BM, the reflectivity becomes very high, and the problem of color deviation is significant

[0234] (1) Preparation of silver nano (nano) particle dispersion: metal-containing dispersion A-1

[0235] 3.0 g of polymer compound PO-1 having the following structure was added to 2.5 L of an aqueous solution adjusted to pH 12.0 using a 1 N aqueous sodium hydroxide solution, and stirred at 45° C. for 30 minutes until it was completely dissolved.

[0236] [chemical 1]

[0237]

[0238] The solution was controlled at a temperature of 45°C, and an aqueous solution containing 8.5 g of ascorbic acid, an aqueous solution containing 5 g of hydroquinone and 1.5 g of sodium sulfite, and an aqueous solution containing 30 g of silver nitrate were added simultaneously to prepare a black silver nanoparticle-containing liquid.

[0239] The obtained silver fine particles were connected particles in which spherical particles having an arithmetic average particle diameter of 16.1 nm and an average aspect ratio of 2.2 were randomly connected. The prepared silver nanoparticle-containing so...

Embodiment 2

[0312] (Manufacturing of liquid crystal display devices)

[0313] Using the substrate on which the obtained black matrix was formed, a liquid crystal display device R-1 was produced by using the method described in the first embodiments [0079] to [0082] of JP-A-11-242243, and it was confirmed that there was no Displayed incorrectly.

[0314] On the other hand, except that the black matrix B-1 was replaced with B-2 to B-8, the liquid crystal display devices R-2 to R-8 were produced in the same manner as the production of the liquid crystal display device R-1, and the results were confirmed to be : Displayed without malfunction.

[0315] "Uneven Evaluation"

[0316] When a gray test signal was input to the liquid crystal display device, the display part was observed visually and with a magnifying glass, and whether or not unevenness occurred was judged. When no unevenness was observed at all, "⊚" was given, when slight unevenness was confirmed, "◯" was given, and when signifi...

Embodiment 3

[0322] On the surface of a polyethylene terephthalate film support (temporary support) with a thickness of 75 μm that is biaxially stretched, a glass substrate coating machine (FAS Asia (エフ·エ一·エス) having a slit-shaped nozzle is used. - Made by Asia) Co., Ltd., trade name: MH-1600), a thermoplastic resin layer coating solution prepared as follows was applied to a thickness of 15 μm, and dried at 100° C. for 5 minutes to form a thermoplastic resin layer. Next, an intermediate layer coating solution having the same composition as the protective layer coating solution in Example 1 was applied thereon so that the dry film thickness became 1.5 μm, and dried at 100° C. for 5 minutes. Form the middle layer. Further, the coating solution for photosensitive light-shielding layer (including metal fine particle dispersion A-1) of Example 1 was applied thereon to a dry film thickness of 0.7 μm, and dried at 100° C. for 5 minutes to form a photosensitive layer. Permanent light-shielding la...
