A liquid crystal display device (1) is provided with: a transistor (10) and a pixel electrode (20) provided to each of a plurality of pixels PX; a plurality of common electrodes (30) arranged in the first direction and the second direction, each common electrode facing the one or more pixel electrodes (20) and being spaced apart from each other; a plurality of gate lines (40) extending in the first direction; a plurality of gate lead-out wires (41) extending in the second direction and connected tothe gate lines (40); and a plurality of data lines (50) extending in the second direction, wherein two gate lines (40) are provided for each boundary between two pixels (PX) adjacent to each other inthe second direction. The plurality of pixels (PX) are composed of a plurality of types of pixels periodically and repeatedly arranged in a first direction, and the plurality of data lines (50) and the plurality of gate lead lines (41) are formed in the same layer, and are periodically and repeatedly provided for each boundary between two pixels (PX) adjacent in the first direction.

Description

technical field [0001] The present application relates to liquid crystal display devices. Background technique [0002] Since the liquid crystal display device can display images with low power consumption, it can be used as an image display device such as a television or a monitor. A liquid crystal display device includes: a transistor provided in each of a plurality of pixels arranged in a matrix; a plurality of gate lines extending in a row direction; and a plurality of data lines extending in a column direction. Also, a gate driver for supplying a gate signal to a plurality of gate lines and a source driver for supplying a data signal to a plurality of source lines are installed in a frame region of the liquid crystal display device. [0003] In general, the gate driver and the source driver are installed on different sides of the frame area, but it is also known that the gate driver and the source driver are installed on the same side of the frame area in order to achi...
