    Abstract: According to an aspect, a detection device includes a plurality of light-receiving elements configured to receive light, and a light guide portion one surface of which faces the light-receiving elements. The light guide portion includes a plurality of light guide paths provided throughout from the one surface to the other surface of the light guide portion, and a light-absorbing portion having higher absorbance of the light than that of the light guide paths. When viewed from a direction in which the light-receiving elements and the light guide portion are stacked, more than one of the light guide paths overlap one of the light-receiving elements.

    Abstract: When normal driving is switched to intermittent driving simultaneously with switching from a video image to a still image, a flicker may occur due to a response delay caused by dielectric anisotropy of liquid crystal. A display device has a first mode (video image driving) in which driving is performed at a first frame frequency and a second mode (still image driving) in which the driving is performed at a second frame frequency lower than the first frame frequency. When the first mode is switched to the second mode, the display device first performs the driving at a frame frequency higher than the second frame frequency for at least one frame and then, the driving is switched to be performed at the second frame frequency.

    Abstract: If a black matrix is thinned down in order to increase the aperture ratio, color mixture is likely to occur in which during monochromatic representation a desired color from relevant sub-pixels and a different color from adjacent sub-pixels appear to be mixed together when viewed obliquely. A display device includes a display panel and a light source. The display panel includes an array substrate, an opposite substrate, and a liquid crystal layer. The opposite substrate includes a first light blocking layer and a colored layer. The array substrate includes a second light blocking layer and a signal wiring layer. The first light blocking layer, the second light blocking layer, and the signal wiring layer are disposed between sub-pixels of different colors. The second light blocking layer is disposed close to the liquid crystal layer. A distance between top surfaces of the first and second light blocking layers is decreased.
