Abstract: A lithium secondary battery includes a cathode including a cathode active material that contains lithium metal oxide particles, an anode facing the cathode, and a non-aqueous electrolyte solution including a non-aqueous organic solvent that contains a fluorine-based organic solvent and a lithium salt. A ratio of the number of moles of lithium contained in each of the lithium metal oxide particles to the total number of moles of metals excluding lithium contained in each of the lithium metal oxide particles is 1.05 or more. A content of the fluorine-based organic solvent is in a range from 5 vol % to 60 vol % based on a total volume of the non-aqueous organic solvent.

Abstract: A display device includes: a first substrate including a display area to emit a light having a peak wavelength from light emitting areas and a non-display area surrounding the display area; and a second substrate including transparent areas overlapping the light emitting areas and to convert the peak wavelength of the light or to transmit the light through the transparent areas. The second substrate includes: a base layer including the transparent areas, an inner light blocking area arranged between the transparent areas, and an outer light blocking area arranged outside the transparent areas; a color filter on the base layer; and a light blocking layer above the color filter and including an outer light blocking layer overlapping the outer light blocking area and an inner light blocking layer overlapping the inner light blocking area.

Abstract: A secondary battery having improved impact resistance is provided. The secondary battery includes a battery case comprising an electrode assembly and an electrolyte accommodated in an accommodation part of the battery case. The secondary battery satisfies following Equation (1): Equation (1): W/S?42. In Equation (1), W is an amount of electrolyte per unit capacity of the secondary battery [unit: g/Ah], and S is a product of a total length [unit: m] and a full width [unit: m] of the electrode assembly.

Abstract: Provided is a pouch secondary battery. The pouch-type secondary battery may include an electrode assembly and a pouch-type battery case. The pouch-type battery case may include a cup part configured to accommodate the electrode assembly, a pair of first sealing parts disposed at both sides of the cup part perpendicular to a length direction, and a second sealing part configured to connect the pair of first sealing parts to each other and disposed at one side of the cup part perpendicular to a width direction. When an area of the first sealing part is A mm2, and a weight of the electrode assembly is B g, a ratio A/B may be about 0.29 or more.

Abstract: A display device includes a display area, a peripheral area disposed outside the display area, and a sealing area disposed outside the peripheral area, a first base substrate, a second base substrate facing the first base substrate, a color filter layer disposed under the first base substrate, a bank layer disposed under the color filter layer, and a sealing member disposed between the bank layer and the second base substrate in the sealing area. The bank layer includes bank patterns defining an opening disposed at least in the sealing area, and the sealing member fills the opening. Each of the bank patterns includes a first surface adjacent to the color filter layer and a second surface opposite to the first surface and adjacent to the sealing member. A width of the second surface is greater than a width of the first surface.
