Abstract: A detection apparatus includes a sensor, a detection circuit, and a light source configured to emit light in a first color, a second color, and a third color. The detection circuit acquires a first output, a second output, and a third output that are outputs of the sensor corresponding to a period when the light in the first color is emitted, a period when the light in the second color is emitted, and a period when the light in the third color is emitted, respectively. The detection circuit adjusts at least two or more of the first, second, and third outputs based on adjustment coefficients derived so as to equalize a fourth output, a fifth output, and a sixth output. The fourth, fifth, and sixth outputs are outputs obtained when the sensor is directly irradiated with the light in the first, second, and third colors from the light source, respectively.

Abstract: A transverse electric field type liquid crystal display panel includes a pair of substrates opposed with a liquid crystal layer interposed therebetween. A plurality of sub-pixels having at least one curved portion in a display area are provided in a matrix on one side of the pair of substrates, and a pair of electrodes having at least one curved portion are formed in the plurality of sub-pixels. A light shield layer shielding a non-display area positioned on an outer peripheral side of the display area and between the plurality of sub-pixels is formed on the other side of the pair of substrates. The light shield layer of the non-display area is formed in a shape in which the outermost peripheral side of the display area is rectangular.

Abstract: According to one embodiment, an illumination device includes light sources, a distributing light guide element and a light guide. The distributing light guide element has a first side surface, a second side surface and light waveguides extending from the first side surface towards the second side surface. The light guide has a third side surface and a first main surface. Each of the light waveguides have a first end portion into which light emitted from a corresponding light source enters, and a second end portion from which the light propagating in the light waveguide is emitted. The light emitted from the second end portion enters the light guide via the second side surface and the third side surface and is emitted from the first main surface.
