摘要： A structure including a first resin layer and a second resin layer sandwiching a self-light emitting element layer, a first stopper layer, a first resin sacrificial layer and a first glass substrate which are stacked on the first resin layer on the opposite side of the self-light emitting element layer, and a second glass substrate stacked on the second resin layer is prepared. The first glass substrate is peeled off from the first resin sacrificial layer by irradiating the first glass substrate with a laser beam. The first resin sacrificial layer is decomposed by a chemical reaction using a gas. The first stopper layer has a resistance to the chemical reaction, and the first resin sacrificial layer is removed while leaving the first stopper layer in a step of decomposing the first resin sacrificial layer.

摘要： First rib layers made of an inorganic material are formed in first frame regions of a first glass substrate. First resin layers are formed in first product regions after the first rib layers are formed. First functional layers which include light emitting element layers as a result of luminance of each of unit pixels forming an image being controlled and sealing layers covering the light emitting element layers are formed on the first rib layers and the first resin layers. The first rib layers and the first functional layers are cut along lines passing through the first frame regions while avoiding the first product regions in order to separate the first product regions from each other. In the step of cutting the first rib layers and the first functional layers, the first rib layers and the sealing layers are cut.

摘要： A circuit unit is provided in which it is possible to connect circuit board to a terminal using a simple operation without removing a passivation film from above the terminal. A metal electrode which conducts with a circuit element is formed above a substrate. Multiple column shaped insulation films are each formed at a uniform pitch in two intersecting directions above the surface of the metal electrode. A metal electrode is formed above the metal electrode including the insulation film. A passivation film is formed on a surface of the metal electrode. Conductive beads are stuck between pairs of projection structured bodies formed on a surface of the passivation film, the passivation film on a side surface of the projection structure is scraped whereby the conductive beads conduct simultaneously with the metal electrode and an electrode formed on the circuit board.

摘要： A glass substrate that corresponds to a plurality of product regions and a first grid region that surrounds each of the plurality of product regions and is grid-like is prepared. A protective film that is harder than the glass substrate is formed in the first grid region. A resin layer is formed so as to cover the protective film and the glass substrate. A part of the resin layer is removed by blast processing in a second grid region that avoids the plurality of product regions, overlaps with the first grid region and surrounds each of the plurality of product regions. A circuit layer is formed on the resin layer. The glass substrate is cut along lines that pass through the second grid region where the part of the resin layer is removed. The glass substrate is peeled off from the resin layer.
