Abstract: Provided is a binder for a secondary battery including a copolymer including repeating units of the Chemical Formula 1, Chemical Formula 2, Chemical Formula 3, and Chemical Formula 4 disclosed herein. When the binder for a secondary battery is applied to a negative electrode and a secondary battery, expansion of the negative electrode may be effectively suppressed. Furthermore, the binder for a secondary battery has improved adhesion to effectively suppress exfoliation and desorption of a negative electrode, thereby manufacturing a secondary battery having significantly improved charge/discharge cycle characteristics and battery performance by using the binder.

Abstract: A hydrogen storage device includes a storage container having an accommodation space in an interior thereof, a first metal hydride material provided in the interior of the storage container and that stores hydrogen, and a second metal hydride material provided in the interior of the storage container and that stores the hydrogen at a pressure that is different from that of the first metal hydride material. An advantageous effect of restraining an excessive rise of a pressure of the storage container and enhancing safety and reliability may be obtained.

Abstract: A hydrogen storage system is disclosed and includes a storage unit including a plurality of unit storage containers, in which metal hydride materials are respectively provided in an interior thereof and which are connected to each other in parallel, and a thermal fluid line defining a thermal fluid passage, which passes via the plurality of unit storage containers continuously and through which a thermal fluid flows for heating or cooling the unit storage containers, thereby enhancing a storage performance and an efficiency of the hydrogen.

Abstract: A display device may include a display panel, at least one optical sheet on the display panel, a light guide plate on the at least one optical sheet, and a bottom chassis having a side surface part on which the display panel is seated, an inner side part having at least one step from the side surface part, the at least one optical sheet and the light guide plate being in the inner side part.

Abstract: A liquid crystal display device includes a black matrix between first and second substrates, the black matrix having openings defined therein, color filters between the first and second substrates and aligned with the openings defined in the black matrix, the color filters including first filters having a first color, second filters having a second color, and third filters having a third color; and spacers configured to maintain a predetermined cell gap. The second filters have a recess, such that the second filters have an area that is less than an area of the first filters, the spacers are aligned with regions of the black matrix adjacent to the recesses in the second filters, and alignment layers are on the first and second substrates.

Abstract: A liquid crystal display device includes a first substrate having a plurality of first electrodes, a second substrate facing the first substrate and having a plurality of second electrodes perpendicular to the first electrodes to define sub-pixels at intersection regions between the first and second electrodes, a liquid crystal layer between the first and second substrates, a plurality of color filters between the first and second substrates adapted to correspond to respective sub-pixels, the color filters including first color filters and second color filters having a different shape than the first color filters, a black matrix between the color filters, the black matrix including vertical portions, horizontal portions, and step portions, each of the step portions corresponding to a respective second color filter, and a plurality of patterned spacers between the first and second substrates, each of the patterned spacers overlaps with a respective step-portion of the black matrix.

Abstract: The present invention relates to a system and method for providing interactive moving picture contents, and more particularly, to a system and method for providing moving picture contents, wherein moving picture contents provided by a user are divided into an original moving picture and additional contents to be stored separately, so that if another user makes a request for using one of previously registered moving picture contents, respective layers created from an original moving picture and additional contents of the relevant moving picture contents are combined and provided to the other user, and at the same time, a function of editing the additional contents for the relevant moving picture is provided to allow users of the moving picture contents other than a user who has initially provided the moving picture contents to easily modify the additional contents or add a variety of additional contents related to the original moving picture.

Abstract: A LCD device includes a first substrate having a plurality of first electrodes, a second substrate having a plurality of second electrodes, the second electrodes being perpendicular to the first electrodes to define sub-pixels at intersection regions between the first and second electrodes, a reflective film between the first and second substrates, each reflective portion being positioned in a respective sub-pixel to define a reflective region and a transmission region in the respective sub-pixel, a plurality of color filters between the first and second substrates, a black matrix between the color filters, and a plurality of patterned spacers between the first and second substrates, each patterned spacer overlapping the reflective portion of the reflective film in the respective sub-pixel.
