1. A transmission type liquid crystal display device comprising:

  • gate lines;

    source lines; and

    switching elements each arranged near a crossing of a gate line and a source line, a gate electrode of a switching element being connected to the gate line, a source electrode of the switching element connected to the source line, and a drain electrode of the switching element connected to a pixel electrode for applying a voltage to a liquid crystal layer, wherein a transparent colorless interlayer organic insulating film, formed from a cured organic polymer and having a thickness determined by a light transmittance and a dielectric constant of the film, is provided above the switching element, the gate line, and the source line, said thickness of the transparent colorless interlayer organic insulating film provides a reduced capacitance between said pixel electrode and said gate line or source line, andsaid pixel electrode is a transparent conductive film on the interlayer insulating film, wherein a spectral transmittance of the transparent interlayer organic insulating film has a lower transmittance for blue light than that for green and red light.
