PROBLEM TO BE SOLVED: To suppress an increase in a parasitic capacitance accompanied by providing a light shielding film and to prevent reflected light in a liquid crystal panel from being made incident to channel layer by providing a reflection preventing film formed from the same material as a light shielding film on a source drain electrode of a thin film transistor via an insulation film. SOLUTION: Light 140 emitted from the glass board 120 side reflects from metal films of the back of the glass board 100 on the opposite side of the incident light, a source electrode 104 a drain electrode 103, etc., and is made incident on a channel layer 102. To shield this incident light and suppress an increase in an off-current, a light shielding film 105 is formed. Since this light shielding film 105 is formed from a-Si (I), the incident light on the channel layer 102 cannot completely be absorbed only by the light shielding film 105 in the case of use in a projection type display device. For this reason, reflection preventing films 207, 208 formed from a-Si(I) are provided on the source electrode 104 and the drain electrode 103 causing light reflection in the panel as well as the light shielding film 105. |
