摘要： A detection cell includes a pair of filter electrodes, disposed separated from and opposing each other. One of the pair of filter electrodes includes a first region provided following a flow direction of an object of measurement introduced between the filter electrodes, and a second region that is provided arrayed with the first region regrading an intersecting direction intersecting the flow direction, and that protrudes to a position at which a distance of separation as to another of the pair of filter electrodes is smaller than that of the first region. First and second downstream-side electrodes are respectively disposed on downstream sides of the first and second regions, in the flow direction, and are separated from each other regarding the intersecting direction. First and second opposing electrodes are disposed on the downstream side from the other of the pair of filter electrodes, and oppose the first and second downstream-side electrodes.

摘要： A display device according to aspect of the disclosure includes: a source driver; and a timing controller. The source driver and the timing controller perform data communication through serial transmission. The display device further includes a storage unit configured to store information about each of a plurality of standards that are different from each other, the standard defining a protocol for specific serial transmission. The timing controller selects one standard from among the plurality of standards, performs first determination that is determination on the selected standard to determine whether to receive a lock signal from the source driver within a predetermined period after training pattern data compatible with the selected standard is output to the source driver, and outputs an image signal of the protocol of the selected standard to the source driver when a result of the first determination is positive.

摘要： Provided is a liquid crystal display device including a first and second sub-pixels and including a first and second substrates. The first substrate includes a common electrode, an interlayer insulating film, and a first and second sub-pixel electrodes. The first and second sub-pixel electrodes each include linear electrode portions at an edge area and a linear electrode portion at a central area. The interlayer insulating film includes a region overlapping the linear electrode portions at the edge area and a region overlapping the linear electrode portion at the central area for each sub-pixel and the regions are different in at least one of a film thickness or a relative permittivity. An electric field strength between the common electrode and the linear electrode portions at the edge area is lower than an electric field strength between the common electrode and the linear electrode portion at the central area.

摘要： A liquid crystal display device includes a first substrate; a second substrate; and a vertical alignment-type liquid crystal layer. The first substrate includes a backplane circuit, a first interlayer insulating layer covering the backplane circuit, a first reflective electrode provided on the first interlayer insulating layer and including a first region located in each of pixels and a second region located between any two adjacent pixels, a second interlayer insulating layer covering the first reflective electrode, and a pixel electrode provided on the second interlayer insulating layer in each pixel. The pixel electrode is electrically connected with the backplane circuit in first and second contact holes formed in the first and second interlayer insulating layers. The first substrate further includes a second reflective electrode provided on the second interlayer insulating layer so as to overlap the first contact hole as seen in a direction normal to a display surface.
