    • The liquid crystal display comprises a first substrate including a first pixel electrode and a second pixel electrode, a second substrate with an opposed electrode formed on, and a liquid crystal layer sealed between the first substrate and the second substrate. The thickness d1 of the liquid crystal layer on the first pixel electrode in the first pixel region is larger than the thickness d2 of the liquid crystal layer on the second pixel electrode in the second pixel region. The first pixel region includes a first partial region and a second partial region where the threshold voltage is higher than in the first partial region. The second pixel region includes a third partial region and a fourth partial region where the threshold voltage is higher than in the third partial region. The threshold voltage in the first partial region and the threshold voltage in the third partial region are equal to each other, and the threshold voltage in the second partial region and the threshold voltage in the fourth partial region are equal to each other. Thus, it is possible to prevent large changes in the chromaticity due to gradation and visual angle changes, which lead to the prevention of the occurrence of the coloring. Thus, it is possible to provide a liquid crystal display having good display quality.
    • 液晶显示器包括包括第一像素电极和第二像素电极的第一衬底,形成有相对电极的第二衬底和密封在第一衬底和第二衬底之间的液晶层。 第一像素区域中的第一像素电极上的液晶层的厚度d1大于第二像素区域中的第二像素电极上的液晶层的厚度d2。 第一像素区域包括第一部分区域和第二部分区域,其中阈值电压高于第一部分区域。 第二像素区域包括阈值电压高于第三部分区域的第三部分区域和第四部分区域。 第一部分区域中的阈值电压和第三部分区域中的阈值电压彼此相等,并且第二部分区域中的阈值电压和第四部分区域中的阈值电压彼此相等。 因此,可以防止由于灰度和视角变化引起的色度的大的变化,这导致防止着色的发生。 因此,可以提供具有良好显示质量的液晶显示器。

    • A lead-free, cream solder composition that is printable includes a SnZn alloy which is lead-free and which is a powder; a solder flux including an epoxy resin; microcapsules that are organic carboxylic acid particles encapsulated with a resin selected from a group consisting of epoxy, polyimide, polycarbonate, polyamide, polyester, polyurea, polyolefin, and polysulfone resins; and a solvent which is a glycol. The presence of the organic carboxylic acid encapsulated with a resin as microcapsules suppresses reactivity of zinc in the SnZn alloy with the organic carboxylic acid Alternately, the solder flux may include the epoxy resin; an organic carboxylic acid; and the solvent; and microcapsules that are particles of a SnZn alloy encapsulated with the described resin. The presence of the SnZn alloy encapsulated with a resin as microcapsules suppresses reactivity of zinc in the SnZn alloy with the organic carboxylic acid so that viscosity and solderability are stabilized.

    • An optical pickup having a first diffractive optical element that acts on light of a specific wavelength, the first diffractive optical element being arranged in an optical path for guiding reflected light from an optical disk to a photodetector. The photodetector comprises a first detector including a first main light receiver divided into a two-by-two square matrix, and a second detector including a second main light receiver divided into a two-by-two square matrix, the second detector being arranged in a row with the first detector. When the light of a specific wavelength is used, zero-order light of the first diffractive optical element is received by the first main light receiver, +first-order light (or −first-order light) diffracted by the first diffractive optical element is received by the second main light receiver, and a tracking error signal is generated using an output signal from the second main light receiver.
