Liquid crystal display device with decorative pattern directly aligned with transparent structured electrodes

A dial assembly for a timepiece comprising a dial and a display device comprising:

• two facing transparent substrates designated respectively front substrate and rear substrate, the front substrate being same disposed on the observer side, the front and rear substrates being directly provided on the inner faces thereof with transparent structured electrodes whereof the superposition defines shape pixels switchable between two optical states, the electrodes being connected to a voltage source via a control circuit, and the two facing transparent substrates forming a cell closed by a sealing frame for receiving a liquid crystal composition in a space delimited by the substrates and the sealing frame;
• a decorative pattern in direct contact with the front substrate and/or the rear substrate;
• and
• the liquid crystal composition, the liquid crystal composition being between the two facing transparent substrates,
• wherein the decorative pattern is aligned with the transparent structured electrodes such that the decorative pattern and a shape of a combination of the shape pixels entirely overlap with each other in a front-rear direction of the display device, such that the decorative pattern does not extend past any lateral end of the combination of the shape pixels and the combination of the shape pixels does not extend past any lateral end of the decorative pattern, and
• wherein the front-rear direction of the display device is a direction in which the front substrate and the rear substrate are stacked.
