摘要： According to an aspect, a display device includes: a display panel including a display area provided with a plurality of pixels; and a light source configured to emit light to the display panel. Writing periods and lighting periods are alternately provided in one frame period for at least one color. Each writing period is a period in which part of a pixel signal is written to a corresponding one of the pixels. Each lighting period is a period in which light is emitted to the pixel after a corresponding one of the writing periods. A light amount in at least one of the lighting periods is larger than a light amount in other lighting periods.

摘要： A method for inspecting a semiconductor device in which each of a plurality of reflective elements includes a liquid crystal. The method includes the steps of acquiring a first capacitance corresponding to each of the plurality of reflective elements after inputting a first voltage signal to the semiconductor device so that a dielectric constant of the liquid crystal is in a predetermined first state in each of the plurality of reflective elements, acquiring a second capacitance corresponding to each of the plurality of reflective elements after inputting a second voltage signal to the semiconductor device so that a dielectric constant of the liquid crystal is in a predetermined second state in each of the plurality of reflective elements, calculating a difference value between the first capacitance and the second capacitance, and determining whether the difference value is less than or equal to a predetermined threshold value.
