Abstract: The liquid crystal display device comprises a liquid crystal cell with liquid crystals sealed thereinbetween, sandwiched between two transparent substrates having an electrode on each of the inner surfaces thereof facing each other, an absorption-type polarizing film disposed on the visible side of the liquid crystal cell, a reflection-type polarizing film disposed on the side of the liquid crystal cell, opposite from the visible side. The absorption-type polarizing film is a polarizing sheet absorbing a light linearly polarized in the direction orthogonal to the transmission axis thereof while the reflection-type polarizing film is a polarizing sheet reflecting a light linearly polarized in the direction orthogonal to the transmission axis thereof. A light reflection film or a color filter may preferably be disposed under the reflection-type polarizing film. Further, a light diffusing layer or a light diffusing film may preferably be disposed on the visible side of the absorption-type polarizing film.

Abstract: A liquid crystal display device is made by disposing an STN cell (16) in which nematic liquid crystal (6) having a twist angle in the range from 180 DEG to 270 DEG is filled and sandwiched between a first substrate (1) having a first electrode (3) and a second substrate (2) having a second electrode (4) at the center, providing a retardation film (13) and an absorption-type polarizing film (8) outside the second substrate (2) in order, and providing a reflection-type polarizing film (10) and a light absorbing film (11) outside the first substrate (1) in order. This enables a metallic silver background due to the reflected light by the reflection-type polarizing film (10) and display in black or in color by light passing through the reflection-type polarizing film (10) being absorbed in the light absorbing film (11) or only light of specific color being reflected.

Abstract: A watch equipped with a liquid crystal display panel for displaying at least either time information or calendar information. A liquid crystal is sealed in a space between two transparent substrates having electrodes on the opposed inner surfaces thereof, and polarizers are provided on the outer sides of the substrates, while a light-absorbing plate is disposed on one polarizer on the side opposite to a liquid crystal cell. The polarizers reflect a linearly polarized light having a plane of vibration perpendicular to the axis of each transmission. Either the background or the display segment shows a metallic color and the other shows the colour of the light-absorbing plate, exhibiting a varied design.
