<p>A known display device consists of a sheet-like support (1) which is covered with liquid thermochromic crystals (2). These are tempered by individual power supply to individual heatable elements (3), which lie close to the crystals and are placed between the sheet-like support (1) and the crystals (2). The crystals assume different shades of colour dependent on the given temperature so that hereby the colour of the crystals will form a certain pattern. In order to improve the possibilities to control the tempering of the individual crystals and also protect them from being effected by the ambient temperature and from mechanical damage, the crystals have underlying means (4) which are controlled to cool down the crystals (2) and/or keep the sheet-like support (1) of the crystals at a certain temperature. This temperature is lower than the temperature, at which the crystals are coloured. Further the crystals are covered by a coating of lacquer over the complete sheet-like support.</p> |
