Abstract
A first light-blocking member and a second light-blocking member are adhered to each other by forming a light-transmitting layer having a light-transmitting composition serving as a base material and a light-transmitting filler different in index of refraction from this light-transmitting composition on a front surface of the first light-blocking member. A liquid light curing adhesive is applied to a front surface of the light-transmitting layer. The second light-blocking member is arranged on the front surface of the light-transmitting layer to which the liquid light curing adhesive has been applied. The liquid light curing adhesive is cured by irradiating the light-transmitting layer with light having a prescribed wavelength laterally from a side of the light-transmitting layer so as to adhere the light-transmitting layer and the second light-blocking member to each other. By adhering light-blocking members to each other, an adhesion operation may easily and quickly be performed with sufficient adhesion strength.
