Abstract
A phosphor reflecting sheet provides a phosphor layer on one side in a thickness direction of a light emitting diode element and provides a reflecting resin layer at the side of the light emitting diode element. The phosphor reflecting sheet includes the phosphor layer and the reflecting resin layer provided on one surface in the thickness direction of the phosphor layer. The reflecting resin layer is formed corresponding to the light emitting diode element so as to be disposed in opposed relation to the side surface of the light emitting diode element.

2. A method for producing a light emitting diode device comprising the steps of:
-
providing a reflecting resin layer on one surface in a thickness direction of a phosphor layer to prepare a phosphor reflecting sheet in which the reflecting resin layer is formed corresponding to the light emitting diode element so as to be disposed in opposed relation to the side surface of the light emitting diode element, providing the light emitting diode element on one surface in the thickness direction of a substrate, forming a through hole in the substrate such that the through hole extends therethrough in the thickness direction thereof; laminating the phosphor reflecting sheet on the substrate so as to dispose the reflecting resin layer in opposed relation to the through hole and dispose the phosphor layer in opposed relation to one surface in the thickness direction of the light emitting diode element, reducing a pressure in the through hole, and bringing the reflecting resin layer into close contact with a side surface of the light emitting diode element. - View Dependent Claims (3, 4)
