Abstract: Provided is a wearable sensor with enhanced light sensitivity. The wearable sensor is to be worn by a subject, the wearable sensor including: a supporting substrate; and sensor elements placed on the supporting substrate. The sensor elements each include: a light emitter which is an organic light emitting diode or an inorganic light emitting diode; and a reflected light receiver configured to measure a quantity of light emitted from the light emitter and reflected in a living body of a subject. Preferably, in a plan view, at least part of the reflected light receiver does not overlap the light emitter.

Abstract: 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.
