Further, a color filter including pixel regions of respective colors of red (R), green (G), and blue (B) is formed inside the substrate on one side. On the color filter, a black matrix is usually formed so as to distinguish each pixel region such as red, green, and blue.

通常，彩色濾光片係藉由微影法而製造。即，首先於基板上塗佈黑色感光性樹脂組合物並使其乾燥後，進行曝光、顯影而形成黑矩陣。其次，對紅色、綠色、藍色等各色之感光性樹脂組合物反覆進行塗佈、乾燥、曝光及顯影，將各色之像素區域形成於特定位置而製造彩色濾光片。 Generally, color filters are manufactured by lithography. That is, first, a black photosensitive resin composition is applied onto a substrate and dried, and then exposed and developed to form a black matrix.

Therefore, it is known that the sensitivity of the photosensitive resin composition is affected by the kind of the photopolymerization initiator contained therein. In addition, in recent years, with the increase in the number of productions of liquid crystal displays and the increase in the production amount of color filters, it is necessary to form a high-sensitivity sensitization pattern with a low exposure amount from the viewpoint of further improving productivity. Resin composition. to In this case, Patent Document 1 discloses various compounds such as an oxime ester compound as a photopolymerization initiator which can improve the sensitivity of the photosensitive resin composition. Specifically, in the examples described in Patent Document 1, compounds represented by the following structural formulae (a) to (d) are disclosed.

根據表1及表2，可知若使用包含通式(1)所表示之肟酯化合物作為光聚合起始劑且包含有彩色著色劑之實施例之感光性組合物，則能夠形成難以自基板剝離，具有變色較少之所需色相，異物較少之著色膜。 According to Tables 1 and 2, it is understood that when a photosensitive composition containing an oxime ester compound represented by the formula (1) as a photopolymerization initiator and containing a coloring agent is used, it is difficult to form a photosensitive composition from the substrate. A color film having a desired hue with less discoloration and less foreign matter.

另一方面，根據比較例，可知於包含有彩色著色劑之感光性組合物中調配除式(1)以外之結構之光聚合起始劑之情形時，著色膜容易因膜形成時之加熱而變色，著色膜中之異物量較多，容易產生著色膜自基板之剝離。 On the other hand, according to the comparative example, when a photopolymerization initiator having a structure other than the formula (1) is blended in the photosensitive composition containing the coloring agent, the colored film is liable to be heated by the film formation. The color is changed, and the amount of foreign matter in the colored film is large, and peeling of the colored film from the substrate is likely to occur.
