Description of the invention: [Technical field to which the invention pertains] The panel is used in the manufacture of a liquid crystal display or an ink for displaying σ or spray 4 . More specifically, the present invention is useful for inkjet printing of the microlens (four) or the like which is suitable for backside printing. [Previous technology] Before the liquid crystal display element of a liquid crystal display or the like is used by using a light source A transmissive or semi-transmissive liquid crystal display element (Lqmd (^ystal Dispiay 'LCD) is shown. Such a transmissive or semi-transmissive LCD is formed by providing an opening in a reflecting plate inside the LCD, from the opening. A structure in which a light source is transmitted through a light source. In this way, a light guide plate in which a microlens array is disposed between a liquid crystal display panel and a light source in order to eliminate uneven brightness is proposed (for example, Japanese Patent Fighting Temple 2003-107505) In the injection molding method which is a method of manufacturing such a light guide plate, it is necessary to produce a plurality of molds, which requires a large amount of time and cost. Moreover, it is manufactured by using the above-mentioned manufacturing method. In the case where the patterning accuracy of the resin lens is poor, it is easy to cause unevenness in brightness. In order to solve these problems, in recent years, it has been developed to directly apply a photosensitive material by an inkjet method. A method of forming a microlens array on a substrate (for example, Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. 2), Japanese Patent Laid-Open No. Hei. No. 2 (M8_5 (Patent Document 3), Japanese Patent Laid-Open No. 2004-240294 No. (Patent Document 4)). In this way, it is easy to control the patterning by using the inkjet 201122000^ ί manufacturing method, even if the electronic data such as the previous mold is not produced, and thus the production is expected to be suppressed. In terms of the manufacturing cost and the like, the photo-sensitive material is used as a method for the ink-jet method, which is disclosed in the Japanese Patent Publication No. 2_4_ (Patent Document 6), JP-A-2006-208734 (Patent Document 7), and 7-Qing Pao (Patent Document 8)), but the microlens array of the above does not have sufficient photocurability: performance against all properties such as adhesion = adhesion, high transmittance, and high strength In the case of the Japanese version, the Japanese version of the Japanese version of the Japanese Patent No. 7_70472 (the patent document Japanese Patent No. 2GG3_192943) (Patent Document 12), 唬报 (Patent Document 15), Japan Japanese Patent Laid-Open No. Hei 2-6562 (Patent Document No. 9), Patent Publication No. JP-A-7 (5) (Publication Document) Specialized Kaiping 7 7〇4<72 5 Tiger Bulletin (Patent Document u) does not have sufficient strength according to the measured transmittance of hard (10). 6 201122000, this i *Japanese Patent Laid-Open No. 2QG3_192943 ( Patent Document No. 2), Japanese Patent Laid-Open Publication No. sho.

Each test method is as follows, and the evaluation results are shown in Tables 1 and 2. (Injection test of ink) The dot pattern on the substrates (la to l〇a, ib to 10b) obtained in each of the examples and the comparative examples and the square pattern of the 3 cm square were observed, and the printed white ink was evaluated. Sex. The evaluation criteria are as follows. 〇 : Completely unpatterned chaos, printed white. △: The pattern is confusing, and the printing is white. x : The ink cannot be ejected (that is, the pattern cannot be formed). (Photohardenability test) The surface of the square pattern substrate (lb to 10b) of 3 cm square obtained in each of the examples and the comparative examples was touched with a finger, and the surface state of the cured film was observed with a microscope. The evaluation criteria are as follows. Ο 〇: The finger touch marks did not remain on the surface of the cured film at all. △: The finger touch trace slightly remained on the surface of the cured film. X: Finger touch marks completely remain on the surface of the cured film. (Measurement of Transmittance of Cured Film) Using a transmittance measuring device V-670 (manufactured by JEOL Ltd.), a 3 cm square square pattern substrate (lb to 10b) obtained in each of the examples and the comparative examples was used to measure the wavelength of light. Transmittance at 400 nm.
