Abstract: A copper foil for a negative electrode current collector of a lithium ion secondary battery enables prevention of deformation of the current collector even if the charge/discharge operation is repeatedly carried out. In a copper foil for a negative electrode current collector of a lithium ion secondary battery, a 10 mm wide test specimen composed of the copper foil is subjected to a tensile test, a maximum strain loaded on the copper foil is 30 N or higher in a region where “Value L” represented by the following expression is 0.

Abstract: A display device includes an array of light emitting cells. Each of the light emitting cells includes a first electrode, a second electrode, and an organic light emitting layer located between the first electrode and the second electrode. Banks are above the first electrode that partition the organic light emitting layer to define each of the light emitting cells. The light emitting cells include a peripheral light emitting cell that is located in a peripheral region of the array. The banks include first and second banks that each border the peripheral light emitting cell. The first bank is closer to a periphery of the array than the second bank. An inclination angle of an innermost sidewall of the first bank that is adjacent the peripheral light emitting cell is greater than an inclination angle of an outermost sidewall of the second bank that is adjacent the peripheral light emitting cell.

Abstract: A display device includes an array of light emitting cells. Banks define each of the light emitting cells. The light emitting cells include a first light emitting cell that is located in a central region of the array and a second light emitting cell that is located in a peripheral region of the array. First and third banks border the first light emitting cell with the first bank being closer to a periphery of the array than the second bank. Second and fourth banks border the second light emitting cell with the third bank being closer to the periphery of the array than the fourth bank. An inclination angle of an innermost sidewall of the third bank that is adjacent the second light emitting cell is different than an inclination angle of an innermost sidewall of the first bank that is adjacent the first light emitting cell.

Abstract: The upper surface portion of a planarization layer is planarized. In an anode formed on the planarization layer, upper surface portions at edge regions by a bank are located above an upper surface portion at a central region. A hole injection transporting layer is layered along the upper surface portions of the anode, and in the hole injection transporting layer, upper surface portions at the edge regions near the bank are located above an upper surface portion at the central region. In an organic light-emitting layer, upper surface portions at the edge regions (regions D1 and D2) near the bank are located above an upper surface portion at the central region (region D3). As a result, thicknesses T11 and T12 of the light-emitting layer are equivalent to a thickness T13 of the organic light-emitting layer.

Abstract: A pixel in the panel includes sub-pixels 100a, 100b, and 100c. Non-light-emitting cells 100d and 100e are provided between the pixel and adjacent pixels on both sides thereof, respectively. The organic light-emitting layer of sub-pixel 100a and non-light-emitting cell 100d are separated by bank 105a. Similarly, the organic light-emitting layer of sub-pixel 100c and non-light-emitting cell 100e are separated by bank 105d; the organic light-emitting layers of sub-pixels 100a and 100b are separated by bank 105b; and the organic light-emitting layers of sub-pixels 100b and 100c are separated by bank 105c. Inclination angle ?aa of sidewall 105aa of bank 105a adjacent to sib-pixel 100a and inclination angle ?dc of sidewall 105dc of bank 105d adjacent to sib-pixel 100c are larger than other inclination angles ?ba, ?bb, ?cb, and ?cc.

Abstract: A non-light-emitting cell 100c is provided between pixels 100a and 100b. Ink for forming an organic light-emitting layer is dripped substantially simultaneously into sub-pixels 100a1, 100a2, and 100a3 in the pixel 100a and a sub-pixel 100b1 in the pixel 100b. On the other hand, such ink is not dripped into the non-light-emitting cell 100c since the organic light-emitting layer is not formed in the non-light-emitting cell 100c. Regarding two banks 105c and 105d defining the sub-pixel 100a3, an inclination angle ?d3 of a wall 105d3 of the bank 105d is larger than an inclination angle ?c3 of a wall 105c3 of the bank 105c. Similarly, regarding banks 105e and 105f defining the sub-pixel 100b1, an inclination angle ?e1 of a wall 105e1 of the bank 105e is larger than an inclination angle ?f1 of a wall 105f1 of the bank 105f.

Abstract: A laminated coil component includes a spiral coil including laminated ceramic films and coil conductors. Pad portions provided at ends of the coil conductors are connected to one another using via-hole conductors to provide an interlayer connection among the pad portions. Thus, a spiral coil is provided. The pad portions are thinner than the coil conductors, and accordingly, a concentration of stress on portions at which the pad portions and the via-hole conductors overlap one another is reduced.

The weight ratio of [the particles/the metallic material] in the half closer to the negative electrode surface is preferably higher than that in the other half farther from the negative electrode surface.
