Abstract: There is provided a backlight device used in a color liquid crystal display device (LCD). The backlight device generates white light by mixing red light, green light, and blue light generated from a light source including a red color light emitting diode (21R) emitting red color light having a half value width hwr: 15 nm ≤ hwr ≤ 30 nm, a green color light emitting diode (21G) emitting green color light having a half value width hwg: 25 nm ≤ hwg ≤ 50 nm, and a blue color light emitting diode (21B) emitting blue color light having a half value width hwb: 15 nm ≤ hwb ≤ 30 nm. The white color light is applied from the rear side of a transmittance type color liquid crystal display panel (10) including a color filter (19) having three primary color filters for wavelength-selectively transmitting red color light, green color light, and blue color light.

Abstract: A color filter (19) is provided to be used in a transmissive color liquid crystal display panel of a color liquid crystal display. The color filter (19) is composed of a three-primary-color filter which selectively transmits red light, green light and blue light by wavelength, and prevents color mixing by preventing the transmitting wavelength range of a red color filter (CFR) from substantially overlapping that of a blue color filter (CFB).

Abstract: A backlight device for illuminating a transmission color liquid crystal display panel with white light from the back side comprising, as a light source, a plurality of main light emitting diode units 21mn (m, n are natural numbers) consisting of a plurality of light emitting diodes (21) arranged in columns and emitting white light with a predetermined chromaticity, and sub-light emitting diode units 21mn, smaller in number than the main light emitting diode units 21mn, consisting of a plurality of light emitting diodes (21) arranged in columns and emitting white light with chromaticity in the vicinity of the predetermined chromaticity. When the sub-light emitting diode units 21mn are arranged in two-dimensional matrix, they are not arranged side by side on the same row, and the sub-light emitting diode units 21mn being arranged in the central column of the two-dimensional matrix are arranged on the central side of a color liquid crystal display panel (110).

Abstract: A magnetic recording medium comprises a nonmagnetic substrate (1), and a magnetic layer consisting of a first ferromagnetic metal thin film (2) of an orthorhombic, columnar structure formed on the nonmagnetic substrate (1), and a second ferromagnetic metal thin film (3) of an orthorhombic, columnar structure. The direction of growth of the orthorhombic, columnar structure of the first ferromagnetic metal thin film (2) and that of the second ferromagnetic metal thin film (3) are opposite to each other. The thickness of the first ferromagnetic metal thin film, the thickness of the second ferromagnetic metal thin film, the coercive force and remanent magnetic flux density of the magnetic layer, the longitudinal stiffness and surface roughness of the back surface of the magnetic recording medium are determined selectively so that the magnetic recording medium is able to function satisfactorily regardless of the direction of movement of the magnetic head relative to the magnetic recording medium in reproducing recoded data by a recording/reproducing apparatus of a nontracking data reproducing system and a nonloading tape drive system.

Abstract: PROBLEM TO BE SOLVED: To provide a high-performance small and lightweight triple-lens image forming lens which is bright with about 3.5 F number, which has the half angle of view as wide as ≥30°, about 0.08 mm astigmatism and about ±0.3% distortion aberration and which is suitably used for an imaging element having ≤5 μm pixel pitch.
SOLUTION: The lens includes, in the order from a larger conjugate side, first to third lenses L1 to L3. The first lens L1 is a positive lens the face of which in the larger conjugate side is a convex face toward the larger conjugate side, the second lens L2 is a negative meniscus lens having a convex face opposing to the smaller conjugate side, and the third lens L3 is a positive meniscus lens having a convex face opposing to the larger conjugate side.
