Title:
発光機能を備えた光透過プレートおよびその製造方法
Document Type and Number:
Japanese Patent JP7085894
Kind Code:
B2
Abstract:
To provide an optically transparent plate improved in light extraction efficiency while having a structure where an LED die is directly mounted on an optically transparent substrate.SOLUTION: An optically transparent plate includes: a first optically transparent substrate 21; a wiring pattern 3 provided on an upper face of the optically transparent substrate 21; an LED die 1 bonded to the wiring pattern 3; a second optically transparent substrate 22 placed on a face of the optically transparent substrate 21, the face being a side opposite to a face where the LED die 1 is mounted; and a reflective film 4 placed in a position sandwiched between the optically transparent substrate 21 and the optically transparent substrate 22. Both of at least a part of the wiring pattern 3 and at least a part of the reflective film 4 comprise a conductive material obtained by sintering conductive particles. The reflective film 4 has an upper face and a lower face which are directly bonded to the optically transparent substrate 21 and the optically transparent substrate 22, respectively, and fixes the optically transparent substrate 22 to the optically transparent substrate 21.SELECTED DRAWING: Figure 1
