  • Patent number: 9837444
    Abstract: A display device is described that has reduced resistance in one or more of the gate, common, data electrical lines that control the operation of the pixels of the display device. Reduced resistance is achieved by forming additional metal and/or metal-alloy layers on the gate, common, and/or data lines in such a manner so that the cross-sectional area of those lines is increased. As a consequence, each such line is formed so as to be thicker than could otherwise be achieving without causing defects in the rubbing process of an alignment layer. Additionally, no widening of these lines is needed, thus preserving the aspect ratio of the device. The gate insulating and semiconducting layers that in part make up the thin film transistors that help control the operation of the pixels of the device may also be designed to take into account the increased thickness of the lines.

  • Patent number: 9770948
    Abstract: A display section displays a shift indicator in a smaller size than that in a normal state at the start of display (upon switching the display) of the shift indicator. After that, the display section gradually enlarges a size of the shift indicator until it has a larger size than that in the normal state, and then gradually reduces the size of the shift indicator until it has the size in the normal state, thereby starting the display of the shift indicator in the size in the normal state. This operation provides a display device through which a driver can readily recognize the current shift position.
