Abstract: Simple and high-precision processing, and narrowing of the frame are to be facilitated at the time of preparing display panels by multiple formation. After bonding a first substrate layer in which a plurality of element substrates is formed on a support plate and a second substrate layer in which a plurality of counter substrates is formed on a support plate, these substrate layers are divided into a plurality of display panels. Ridge-like ribs of a covalently or ionically bonding inorganic material are formed along edges of the element substrate and the counter substrate. The dividing includes scribing the support plates along the ribs, and flexing and breaking the support plates.

Abstract: 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.

Abstract: A display device includes a side light type backlight for white color display by single color LEDs, an LED set is placed in a concave portion of a light guide plate, in which a first color LED is located in the center and a second or third color LED is located on the side of the first color LED. An incident slit with an arc shaped convex portion is formed facing the first color LED, and a saw tooth slit with a right-angled triangular concave portion is formed facing the second or third color LED. This allows directing the distribution axes of the lights from the second and third color LEDs to the center side, and adjusting orientation angles to allow effective mixing of the three color lights, in order to increase the white color area and effective display area.
