A display device includes a display panel unit and a backlight unit which radiates light toward the display panel. The display panel unit includes a display panel on an upper surface of a box-shaped panel housing which has first projecting portions on side walls of the housing. The backlight unit incorporates a light source in a bottom portion of a box-shaped light source housing which has second projecting portions on side walls of the light source housing. By bringing the first projecting portions and second projecting portions into contact with each other, a distance between the light source of the backlight unit and the display panel can be held. Further, by forming third projecting portions which project further than the first projecting portions on the panel housing, handling of the display panel unit is facilitated.

A color luminance meter 1 is provided with a polychrometer 4 as a spectral optical system including a light receiving sensor array 43, a signal processing circuit 5 and an operation control unit 6. The operation control unit 6 carries out calculations to obtain characteristics of a measurement light based on a specified spectral responsitivity, using light reception signals and specified weighting coefficients. The spectral responsitivities of light receiving sensors constructing the light receiving sensor array 43 are selected such that B≧5 nm and A/B lies within a range of 1.5 to 4.0 when A, B denote the half power band width of the spectral responsitivities and a center wavelength interval of the spectral responsitivities. Accordingly, there can be provided a light measuring apparatus capable of maximally suppressing errors to highly precisely measure color luminance values and the like even in a measurement of a light lying in a narrow band such as a monochromatic light.
