Abstract: A method for forming a shape of an electro-optical component or photovoltaic component, the method comprising: ultrasonically cutting a substrate using an ultrasonic cutting machine having a holder adapter operatively connected to a shape mould having a contact edge corresponding to the shape, the contact edge making contact with the substrate at a contact region; and spraying a grinding fluid to the contact region; wherein after a predetermined amount of time of ultrasonically cutting the substrate, the component is formed corresponding to the shape.

Abstract: A method for joining sheets (20, 30) to form an electro-optical component, the method comprising: sealing a substantial peripheral portion of the sheets (20, 30) together leaving only an aperture (41) for access to a space defined between the sheets (20, 30); removing air between the sheets (20, 30) via the aperture (41) to create a vacuum between the sheets (20, 30); and filling the vacuum created between the substantially sealed sheets (20, 30) with an adhesive introduced via the aperture (41).

Abstract: A liquid crystal display device (LCD) comprises two supporting plates (1, 2) which are interconnected by means of a sealing edge (3) and enclose a layer of liquid crystalline material (4). Inter alia, for an improved support upon scratching and breaking of the device, the sealing edge (3) is circumferentially provided with protrusions (3A-3D) which extend from the sealing edge (3) substantially to the edge (11) of at least one of the two supporting plates (1, 2).
