Embodiment Construction
[0040] figure 1 is a cross-sectional view of a liquid crystal display device generally indicated by reference numeral 1 . The liquid crystal display device 1 comprises a liquid crystal cell 2 comprising a transparent front substrate 4 on the side of an observer 6 and a also transparent rear substrate 8 , which is parallel to the front substrate 4 below the front substrate 4 and parallel to the front substrate 4 . The front substrate 4 extends at a distance. The two substrates, the front substrate 4 and the rear substrate 8, are connected together by a sealing frame 10 which defines a sealing casing 12 in which the liquid crystal composition is confined. The front substrate 4 and the rear substrate 8 are coated with conductive transparent electrodes 14 and counter electrodes 16 on their opposite surfaces. The optical properties of the liquid crystal composition are changed by applying an electric field at the intersection between the electrodes 14 and the corresponding counte...

The present invention relates to a method for manufacturing a liquid crystal display device (1) of reflective or semi-transmissive and semi-reflective type comprising a liquid crystal cell (2) comprising a transparent front substrate (4) and a transparent rear substrate (8) on the side of the observer (6), the liquid crystal display device (1) being provided with a reflective polarizing film (24) comprising an absorbing polarizer (32), the invention relates to a method for producing a liquid crystal cell (2) comprising an absorbing polarizer (32) in combination with an at least partially reflective reflector (34) arranged beneath it, comprising the steps of forming the reflector (34) into a relief structure to have a decorative and / or functional shape visible to an observer (6) through a front substrate (4) of the liquid crystal cell (2), then fixing the reflector (34) beneath the absorbing polarizer (32), and forming the reflector (34) into a relief structure to have a decorative and / or functional shape visible to the observer (6) through the front substrate (4) of the liquid crystal cell (2). The absorption polarizer itself is fixed against the lower surface (28) of the rear substrate (8).
Description
technical field [0001] The present invention relates to a method of manufacturing a liquid crystal display device and in particular to a liquid crystal display device obtained by means of the method. In particular, the present invention relates to a method of manufacture which allows to provide a liquid crystal display device having a decorative and / or functional pattern which is perceptible through the transparent display surface of the liquid crystal display device. Background technique [0002] The present invention relates to a display device of the digital type, that is, a display device capable of displaying information in alphanumeric form, as opposed to an analog display device which displays information by means of one or more hands that move relative to a scale. [0003] A well-known type of digital display device is the liquid crystal display device. These liquid crystal display devices typically include a liquid crystal cell formed of a transparent front substra...
