A liquid crystal display comprising: a first liquid crystal panel comprising a first substrate and a second substrate which are disposed opposite each other, and a first liquid crystal layer of a polymer dispersed type or a polymer network type sandwiched between the first and second substrates (20, 21); a second liquid crystal panel comprising third and fourth substrates (30, 31) which are disposed opposite each other, a second liquid crystal layer sandwiched between the third and fourth substrates (30, 31), a color filter provided on the third substrate, and first and second polarizing plates (42, 44) provided on the third and fourth substrates (30, 31), respectively; an air layer sandwiched between the first and second liquid crystal panels (12, 14) and in contact with the second substrate, the refractive index of the air layer being set different from the refractive index of the second substrate, and the air layer being in contact with the first and second liquid crystal panels (12, 14); a seal member by which the air layer is sealed between the first liquid crystal panel and the second liquid crystal panel; a backlight provided to face the second liquid crystal panel and being configured to emit light toward the second liquid crystal panel; and a controller configured to control the operations for a character display and for an information display, wherein for the character display, the first liquid crystal panel performs a display operation, while the second liquid crystal panel is in an off state such that the second liquid crystal panel provides black display, and the backlight is off, and for the information display, the entire display surface of the first liquid crystal panel is set to a transmissive state, the second liquid crystal panel is driven, and the backlight is turned on, such that for the character display, when light enters the first liquid crystal panel from the display surface side, said light transmits straight through to the second liquid crystal panel in the areas in the on state and scatters in the areas in the off state, whereby the scattered light having reached the second substrate is reflected by the interface between the second substrate and the air layer. a first liquid crystal panel comprising a first substrate and a second substrate which are disposed opposite each other, and a first liquid crystal layer of a polymer dispersed type or a polymer network type sandwiched between the first and second substrates (20, 21); a second liquid crystal panel comprising third and fourth substrates (30, 31) which are disposed opposite each other, a second liquid crystal layer sandwiched between the third and fourth substrates (30, 31), a color filter provided on the third substrate, and first and second polarizing plates (42, 44) provided on the third and fourth substrates (30, 31), respectively; an air layer sandwiched between the first and second liquid crystal panels (12, 14) and in contact with the second substrate, the refractive index of the air layer being set different from the refractive index of the second substrate, and the air layer being in contact with the first and second liquid crystal panels (12, 14); a seal member by which the air layer is sealed between the first liquid crystal panel and the second liquid crystal panel; a backlight provided to face the second liquid crystal panel and being configured to emit light toward the second liquid crystal panel; and a controller configured to control the operations for a character display and for an information display, wherein for the character display, the first liquid crystal panel performs a display operation, while the second liquid crystal panel is in an off state such that the second liquid crystal panel provides black display, and the backlight is off, and for the information display, the entire display surface of the first liquid crystal panel is set to a transmissive state, the second liquid crystal panel is driven, and the backlight is turned on, such that for the character display, when light enters the first liquid crystal panel from the display surface side, said light transmits straight through to the second liquid crystal panel in the areas in the on state and scatters in the areas in the off state, whereby the scattered light having reached the second substrate is reflected by the interface between the second substrate and the air layer.
