Patent ID: 7764330

Claim:
A liquid crystal display device including pixel portions arranged in a matrix, wherein a normal transistor, connected to both a data signal line and to a pixel electrode, and a spare transistor, that is not connected to both the data signal line and the pixel electrode, are disposed in each of the pixel portions, wherein the liquid crystal display device is configured so that, upon detection that the normal transistor is operating abnormally, the normal transistor can be disconnected from the data signal line by providing a first disconnecting cut of a line connecting the normal transistor and the data signal line along a line substantially parallel with the data signal line, wherein such a first disconnecting cut can be provided so as to be separated from any gate line edges of a gate line of the liquid crystal display device, wherein the line connecting the normal transistor and the data signal line is located within an area between the gate line edges of the gate line, and further wherein the liquid crystal display device is configured so that the normal transistor can be disconnected from the pixel electrode by providing a second disconnecting cut along a line that is substantially parallel with the gate line of the normal transistor.
