Abstract: A display panel and display device are provided that may be capable of sensing an external light source, such as a laser. The display device may include a display panel including gate lines, data lines, and sub-pixels defined at intersections between the gate lines and the data lines; a light source-sensing circuit in an inactive area of the sub-pixels to sense an external light source; and a monochromatic color filter pattern disposed on a sensor transistor of the light source-sensing circuit. Thus, the incident amount of an external light source other than a laser can be reduced, and the incident amount of the laser can be increased. Accordingly, it may be possible to decrease an initial off-current caused by an external light source and improve the sensitivity in laser sensing. Thus, the size of the sensor transistor can be reduced and aperture ratio can be increased.

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.
