    • The present invention provides an illumination device capable of improving an efficiency of acquiring light emitted by light emitting diodes, which are provided in a light source module and used as a light source, and capable of achieving a uniform luminance distribution, and provides a liquid crystal display device using the illumination device. The illumination device includes a circuit board, red, green and blue light emitting diodes, and a lens body. Each red, green and blue light emitting diode is mounted on the circuit board and connected with a wiring pattern formed on the circuit board. The lens covers the red, green and blue light emitting diodes, and includes first portions each having two first side surfaces and second portions each having two second side surfaces. The first and second portions are alternately arranged. A distance between the first side surfaces is larger than a distance between the second side surfaces. The three red, green and blue light emitting diodes are provided in each first portion of the lens.

    • A liquid crystal display (LCD) panel with a backlight module including a light-emitting diode (LED)-based illumination device is disclosed. The illumination device includes more than one LED of the waveguide type for use as a light source of the backlight. The LCD panel includes a pair of substrates, a liquid crystal (LC) layer interposed between these substrates, and a polarization plate. Output light of the LED is linearly polarized in advance. A waveguide is arranged for giving off polarized light components from the LED only in a chosen direction to thereby permit incidence in parallel with a polarized light transmission direction of the LCD polarizer plate. The LED is amounted and arranged so that the polarized light transmission direction of the polarizer plate is the same as the polarization direction through an optical system associated therewith.
    • 公开了一种具有背光模块的液晶显示器(LCD)面板,该背光模块包括基于发光二极管(LED)的照明装置。 该照明装置包括不止一个用作背光源的光源的波导型LED。 LCD面板包括一对基板,插入在这些基板之间的液晶(LC)层和偏振板。 LED的输出光预先线性极化。 波导被布置成仅沿着选定的方向从LED发出偏振光分量,从而允许与LCD偏振片的偏振光透射方向平行地入射。 LED的量被设置为使得偏振片的偏振光透射方向与通过与其相关联的光学系统的偏振方向相同。
