TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The device element is one of an organic electroluminescent device, an organic transistor device or a solar cell device. Preferred Method: In the method (M1), the light blocking layer is formed by vapor deposition of aluminum. The method (M1) further comprises forming a focus position-indicating mark on the support for focusing light onto the photothermal conversion layer.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The adhesive layer is formed so that it further covers the side surface of the photothermal conversion layer. The light blocking layer functions as a light reflecting layer. In the laminate: a focus position-indicating mark for focusing light onto the photothermal conversion layer is provided on the support; and a glass substrate is used as the flexible substrate, a region in which the device element is not formed is present in a peripheral area of the flexible substrate, and a cut that surrounds the device element is provided in the region of the flexible substrate. EXAMPLE - Resin precursor solution of a UV curable acrylic resin containing a photo polymerization initiator and carbon blacks was prepared, and the solution was applied onto the support by spin coating. Then the coating was irradiated with UV light to cure the resin to form photothermal conversion layer of 1 mu m thickness. Aluminum was deposited onto the photothermal conversion layer by vacuum vapor deposition to form a 300 nm thick aluminum film as a light blocking layer. Then a UV curable acrylic adhesive was applied by screen printing onto the light blocking layer and onto the peripheral area of the photothermal conversion layer where the light blocking layer was not present, thus forming the adhesive layer. Then a thin glass having a thickness of 100 mu m as a flexible substrate was placed on the uncured adhesive layer and irradiated with UV light to cure the adhesive layer. Then organic electroluminescent (EL) device was produced by forming an anode, a hole transport layer, a light-emitting layer and a cathode on the flexible substrate. Indium tin oxide (ITO) electrode was used as the anode, and patterning for the electrode was carried out by acid etching. Then a cathode separator for separation of the cathode was formed by alkali development to form each pixel of the organic EL device. Then a sealing substrate (gas barrier film) was attached to the device so that it covers the cathode side, and a flexible printed circuit was connected to the ITO electrode for interconnection, to obtain the laminate.
