Stray light in an oblique direction penetrates a channel part of a thin-film transistor, which sometimes causes light leakage current. This phenomenon becomes more pronounced in the case of using an optical system with high intensity, leading to deterioration in an image quality.To prevent the light that possibly penetrates an equivalent optical waveguide from reaching the channel part, on the condition that a first insulating layer is set to have a layer-thickness t (nm) and a refraction index n, a relation is to be expressed by the following expression. t<(0.61×λ) / (n×sin θ) A value of λ is set to a lower limit 400 (nm) of a visible light wavelength and a value Lc (nm) is set to a distance between an end of a light-shielding layer and an end of a channel region. With those values, an expression of nt2 / 244 (nm)<Lc (nm) is set up. By controlling a layer-thickness of the first insulating layer and a distance between the end of the light-shielding layer and the end of the channel region in a manner to fulfill the above expression, the deterioration in the image quality due to the stray light in the oblique direction can be minimized.
