[0032] 前述评价用粘合剂是用于评价光学部件的接触角的粘合剂,并不一定要由该粘合剂构成图像显示装置的粘合剂层。 [0032] Evaluation of the adhesive binder for the evaluation of contact angle of the optical member, not necessarily formed of the pressure-sensitive adhesive layer of pressure-sensitive adhesive of the image display apparatus. 该评价用粘合剂如前述那样,以异戊二烯聚合物为主要成分,含甲基丙烯酸二环戊烯基氧乙基酯14重量%、甲基丙烯酸苄酯8重量%、甲基丙烯酸甲酯2重量%及光聚合引发剂0.2重量%。 The evaluation as described above with an adhesive, isoprene polymer as a main component, methacrylic acid containing 14 wt dicyclopentenyl oxyethyl% acrylate, benzyl methacrylate 8% by weight methacrylic acid methyl 2 wt% and a photopolymerization initiator 0.2 wt%. 这里所说的光聚合引发剂可以采用艳佳固184(Irgacure 184)等以往公知的聚合引发剂。 Here photopolymerization initiator Irgacure 184 (Irgacure 184) and other conventionally known polymerization initiators can be employed. 评价用粘合剂的其他添加物除了丙酮、2,4,6 —三甲基苯甲酸之类的溶剂、I 一辛硫醇之类的聚合调节剂以外,还可含有二苯基膦,但是,实质上,除了前述必须成分以外,其他成分全部或基本由异戊二烯聚合物构成。 Evaluation of other additives in addition to binder acetone, 2,4,6 - trimethyl benzoic acid and the like solvents, other than I-octene polymerization regulators such as mercaptans, may also contain diphenylphosphine, but substantially, in addition to the aforementioned essential ingredients, other ingredients all or substantially consists of an isoprene polymer. 由于评价用粘合剂由这样的成分构成,因此是透明的,具有粘性。 Since such evaluation is constituted by a component with an adhesive, and therefore are transparent, viscous.

[0033] 本发明的光学部件在向其表面滴入前述评价用粘合剂10 μ I后放置5分钟时,光学部件表面与评价用粘合剂的接触角在55°以下。 Contact angle [0033] The optical member according to the present invention in the evaluation added dropwise thereto with an adhesive surface after placing 10 μ I 5 min and evaluation of the optical member with an adhesive surface of 55 ° or less. 该接触角的测定虽然使用评价用粘合剂,但也可按与水接触角同样的方法进行测定,例如,可以使用DataPhysics公司的Contact Angle System “0CA30L” 进行测定。 Although the contact angle is measured using the evaluation binder, but can also be a contact angle with water was measured in the same manner, for example, may be used DataPhysics Company Contact Angle System "0CA30L" was measured.

[0034] 本发明的光学部件的前述接触角在55°以下,由此可以抑制前述气泡的发生。 [0034] The contact angle of the optical member of the present invention is 55 ° or less, thereby suppressing the occurrence of the air bubbles. 从抑制气泡发生的角度考虑,优选接触角在50°以下。 From the perspective of suppressing the generation of bubbles, it is preferable contact angle 50 ° or less.

[0035] 本发明的光学部件优选还满足下述(2)的条件: [0035] The optical member of the present invention preferably further satisfies the following condition (2):
