Liquid crystal display device

A display device comprising:

• a first liquid crystal panel configured to display an image to be seen by the observer;
• and
• a second liquid crystal panel laid on the first liquid crystal panel, the second liquid crystal panel including pixels a natural number times as large as pixels of the first liquid crystal panel,
• wherein the second liquid crystal panel includes:
• a black matrix defining pixels;
• a plurality of opaque gate lines disposed to be distant from one another in a first direction;
• and
• a plurality of opaque data lines disposed to be distant from one another in a second direction different from the first direction,
• wherein at least either the plurality of gate lines or the plurality of data lines pass through the pixels,
• wherein lines of the black matrix disposed to be distant from one another in the first direction and the gate lines constitute dark lines disposed at a specified pitch in the first direction, and
• wherein lines of the black matrix disposed to be distant from one another in the second direction and the data lines constitute dark lines disposed at a specified pitch in the second direction.
