Abstract: A packaging bag is a packaging bag made of a laminate formed in a bag shape which is in a rectangular shape in plan view, the laminate being composed of a sheet-shaped substrate made of a resin, a cushioning material made of a foamed resin sheet laminated on an inner side relative to the substrate, and a sealant layer laminated on an inner side relative to the cushioning material. The packaging bag includes a seal section in which the sealant layers are sealed to each other on one end edge in a flow direction (MD direction) of the foamed resin sheet, the seal section extending in a direction perpendicular to the flow direction of the foamed resin sheet, wherein a notch is formed in the seal section to be oriented to the other end edge in the flow direction of the foamed resin sheet.

Abstract: The packaging bag is a packaging bag made of a laminate formed in a bag shape, the laminate being composed of a paper substrate, a foamed sheet made of polyolefin resin laminated on an inner side relative to the paper substrate, and a sealant layer laminated on an inner side relative to the foamed sheet, which are laminated with the sealant layer facing inward. In the packaging bag, a thickness of the foamed sheet is in a range of 0.8 mm to 5.0 mm, an expansion ratio of the foamed sheet is in a range of 15 to 50 times, and a bending stiffness of the paper substrate in an MD direction is in a range of 150 mN to 700 mN.

Abstract: A projection type video display apparatus is configured to include a projection optical system, an image processor, and a controller. The controller is configured to control the image processor to perform a blending process for partially changing the brightness of projection videos. The controller is configured to perform control to set a mode of the projection type video display apparatus to a blending adjustment mode in which a user adjusts the blending process performed by the image processor. In the blending adjustment mode, the controller is configured to perform control to generate a menu image of the blending adjustment menu and display the menu image in the projection video. In the blending adjustment mode, the controller automatically changes a display position of the blending adjustment menu according to a position of a blending adjustment region that is a region to be adjusted by the blending process.

Abstract: A color filter includes at least one blue filter segment, at least one red filter segment, and at least one green filter segment, and has a thickness of from 1 to 2.5 &mgr;m. The blue filter segment is prepared from a blue-colored composition containing a colorant carrier selected from the group consisting of a transparent resin, a precursor of a transparent resin and a mixture thereof, and a blue colorant dispersed in the carrier. The blue colorant consists of a copper phthalocyanine pigment and a dioxazine violet pigment. The content of the dioxazine violet pigment is 0.5% to 7% by weight based on the total weight of the blue colorant. There is also disclosed a color liquid crystal display device having the color filter, and a backlight unit provided with a three-band fluorescent lamp as a light source and exhibiting a specific light intensity distribution.
