Abstract: A custom made liquid crystal display is formed from a pre-manufactured liquid crystal display by removing an excess region. The driver card is cut along the line X-X and the excess TABs are disconnected from the conductive layer. Optionally, a narrow strip is removed from each of the polarizing substrates between the lines to expose their associated glass plates. A groove is then cut into the exposed surface of each of the glass plates. Each glass plate is then fractured along the base of its groove so that the excess region is detached from the operative region. The cut edges of the glass plates are then sealed by applying a bead of ultra-violet curing adhesive. The processes of removing an excess region by cutting the glass plates with a laser or by freezing the liquid crystal between the glass-plates and machining through the glass plates are also described.
