A liquid crystal display device is realized which is improved in light reflectivity on pixel electrodes to provide brightness at low cost and low power consumption. A dielectric multi-layered film having a first dielectric film (low refractive film) 105 and a second dielectric film (high refractive film) 106 is formed on a pixel electrode 104 connected to a TFT 102 formed on a substrate 101 having an insulation surface. This dielectric multi-layered film is determined in refractive index (n), center wavelength (.lambda.) and film thickens (d) according to an equation nd=.lambda./4, to give an enhanced reflection effect.
