Problems solved by technology

Due to the existence of the light-shielding layer, the irradiation of ultraviolet rays to the photocurable resin composition sandwiched between the light-shielding layer and the image display member may become insufficient, and the curing may not proceed sufficiently.
As a result, sufficient adhesive force between the members cannot be obtained, and peeling between the light-transmitting cover member and the image display member may occur, and degradation of image quality due to intrusion of moisture into the gap may occur.

Embodiment 1～13 and comparative example 1～4

[0266] The above-mentioned raw materials (A) to (D) were blended with the formulation composition (mass %) shown in Table 1, and heated and stirred at 90°C for 30 minutes to prepare Examples 1 to 13 and Comparative Examples 1 to 1. 4. The photocurable resin composition. In addition, the numerical value about (A)-(D)component in Table 1 means the mass % with respect to the photocurable resin composition whole quantity.

[0267]

[0268] As can be seen from Table 1, in the photocurable resin compositions of Examples 1 to 13, in particular, by adjusting the content of the photopolymerization initiator within the range of the present invention, subsequent steps are not required, and there is no occurrence of the image display member and the light. The liquid of the light-transmitting cured resin layer floats before lamination of the transmissive covering member, and the adhesive force after the members are bonded together via the light-transmitting cured resin layer is also goo...

Abstract

The present invention relates to a photocurable resin composition which contains (A) a compound having a (meth)acryloyl group, (B) a photopolymerization initiator and (C) a plasticizer, and wherein the content of the photopolymerization initiator (B) is 4.0-10% by mass.

Description

technical field [0001] The present invention relates to a photocurable resin composition, an image display device using the same, and a method for producing an image display device. Background technique [0002] An image display device such as a liquid crystal display panel used in an information terminal such as a smartphone is manufactured by disposing a photocurable resin composition between an image display member such as a liquid crystal display panel or an organic EL panel and a light-transmitting cover member, Thereafter, the composition is cured by irradiating ultraviolet rays to form a light-transmitting cured resin layer, thereby bonding and laminating the image display member and the light-transmitting cover member (Patent Document 1). [0003] However, a light-shielding layer is provided on the peripheral portion of the image display member-side surface of the light-transmissive covering member in order to improve the brightness and contrast of a displayed image....
