Abstract: According to an embodiment of the present disclosure, an anodizable aluminum clad sheet may comprise a base material including a 7xxx-series aluminum alloy and a coat material including a 6xxx-series aluminum alloy or a 1xxx-series aluminum alloy disposed on one or both front and back surfaces of the base material, wherein the 7xxx-series aluminum alloy includes 4.0% to 8.0% of zinc (Zn) relative to a total weight of the aluminum clad sheet, 1.0% to 3.0% of magnesium (Mg) relative to the total weight of the aluminum clad sheet, and the rest being aluminum (Al) and at least one other impurity. According to an embodiment of the present disclosure, a method for manufacturing an aluminum clad sheet may enhance the adhesion strength of the clad sheet by employing thermal treatment after forming the clad sheet and may age-harden the clad sheet without deteriorating strength, thereby achieving superior surface and engineering properties.

Abstract: An LCD includes an LCD panel, a light guiding plate including a light guiding plate main body disposed behind the LCD panel and a reflective polarizing layer formed on a surface of the light guiding plate main body to face the LCD panel, and a light source disposed on at least one side of the light guiding plate. The LCD has a high light efficiency by using a light guiding plate since a reflective polarizing layer is formed on the light guiding plate.

Abstract: A device for opening and closing a trunk lid comprises: a trunk lid opening/closing switch operated between an opening mode and a closing mode; a cylinder having one end rotatably fixed to a body panel; a piston dividing a space within the cylinder into a first chamber and a second chamber; a piston rod having one end rotatably fixed to the trunk lid; and a pneumatic section for selectively supplying compressed air into one of the first and second chambers and discharging air in the other one of the first and second chambers, out of the cylinder, according to an operation of the trunk lid opening/closing switch.
