Embodiment Construction

[0040] Below, refer to Figure 1 ~ Figure 4 One embodiment of the present invention will be described.

[0041] figure 2 It is a figure showing the structure of the display device 1 which concerns on one Embodiment of this invention. As shown in the figure, the display device 1 includes a display panel 2 . In the present embodiment, the display panel 2 is a liquid crystal display panel that performs display using changes in the alignment state of liquid crystals, and therefore the display device 1 is a so-called liquid crystal display device. However, the present invention is not limited to the display panel 2 and the display device 1 using liquid crystals.

[0042] figure 1 It is a diagram showing a partial structure of an active matrix substrate 3 according to an embodiment of the present invention. As shown in the figure, the active matrix substrate 3 includes a plurality of pixels 5 , a plurality of dummy pixels 6 , a plurality of dummy pixels 8 , a plurality of dummy ...

Abstract

The invention provides an active matrix substrate. The active matrix substrate (3) is provided with a plurality of pixels (5) configuring a display region (4), and a plurality of dummy pixels (6, 8, 10 and 12) arranged around the display region (4). In the active matrix substrate (3), a diagonal pattern (14) composed of a plurality of diagonal wirings having a fixed width is formed on each of the pixels (5), and at least one measuring pattern composed of a plurality of vertical wirings or horizontal wirings having a width same as the fixed width is formed on at least one of the dummy pixels (6, 8, 10 and 12). Therefore, pattern line width measurement and alignment correction are made possible without increasing a frame region of the active matrix substrate (3).

Description

technical field [0001] The present invention relates to an active matrix substrate having a structure in which dummy pixels are arranged around a display area, a display panel including the active matrix substrate, and a display device including the display panel. Background technique [0002] Conventionally, in liquid crystal display devices, various studies have been conducted in order to improve the reliability of display quality. One of them is the utilization of pseudo-pixels. The dummy pixels are provided outside the display area of ​​the liquid crystal panel, but are not used for actual display. Patent Document 1 discloses an example of a liquid crystal display device using dummy pixels. [0003] In Patent Document 1, an active matrix liquid crystal display device is disclosed, which is characterized in that the shape of the pixel electrodes arranged on the outermost periphery of the first substrate is smaller than that of other pixel electrodes, and the outermost s...
