  • Publication number: 20130050623
    Abstract: It is possible to prevent a decrease in contrast due to external light reflection and to implement a small-size, thin apparatus. The liquid crystal display is configured by interposing alignment films and liquid crystal between a first substrate and a second substrate and adhering the first and second substrates through a gap retaining member and a sealant, wherein the first substrate is a substrate where a light blocking layer, a coloration layer, and a common electrode layer are formed on a plastic film substrate, wherein the second substrate is a substrate where a glass substrate where an active device is formed in advance adhered on a plastic film substrate, and wherein a barrier film is formed on one surface or two surfaces of at least one of the plastic film substrates.

  • Publication number: 20090272726
    Abstract: [PROBLEM] A thin film laminated substrate is cut by a laser beam under certain conditions, so that a cut surface which is sufficient for a display apparatus can be obtained without damaging the thin film laminated substrate, and the cutting is enabled by a low-output inexpensive apparatus, so that a reduction in cost can be expected. [Solving Means] In a display apparatus manufacturing method for emitting a laser beam 43 to the thin film laminate substrate 1 to be used for the display apparatus so as to cut the thin film laminated substrate 1, machining conditions of the laser beam are such that an output of the laser beam is 12 to 18 W, a cutting speed of the laser beam is 130 to 170 mm/sec. and the number of repetitive emitting times of the laser beam is 10 to 15 times, and the laser beam 43 is emitted from at least one surface of the thin film laminated substrate 1 so that the thin film laminated substrate 1 is cut.

  • Patent number: 6284307
    Abstract: A positive hole transporting layer (14) is formed on an ITO film so as to form a substrate (10). A light emission organic material (20) is formed on the front surface of a convex protrusion portion (18) of a metal sheet (16). The front surface of the positive hole transporting layer (14) and the convex protrusion portion (18) are clamped with a glass plate (22). Laser light is radiated to the interior of the convex protrusion portion (18) through a shielding plate with an opening portion whose size corresponds to the size of the convex protrusion portion (18). The light emission organic material formed on the front surface of the convex protrusion portion (18) sublimates and transfers to the positive hole transporting layer (14). These steps are performed for areas of three color light emission devices.
