Active-matrix liquid crystal display

An active-matrix type liquid crystal display device comprising:

• transparent substrates opposed to each other;
• a liquid crystal layer interposed between the opposed transparent substrates;
• pixel areas arranged on the surface of one of the transparent substrates on the liquid crystal side;
• and
• display electrodes, scan signal lines, video signal lines and active devices arranged in the pixel areas;
• and
• a light shielding layer which is an electrically conductive member is provided on the other transparent substrate and applied a certain potential;
• wherein a voltage is applied between the display electrodes and the light shielding layer to produce in the liquid crystal layer an electric field having a component parallel to the transparent substrates to modulate light passing through the liquid crystal layer;
• wherein the light shielding layer has a reflectance of about 10% or less on the display surface side.
