Problems solved by technology

[0009] Therefore, focusing on the slit width, if the slit width is small, cutting marks will be generated especially at the corners (positions where the laser scanning direction is changed), and reliable cutting may occur, resulting in correction defects.
On the other hand, in order to prevent the above-mentioned correction defect, if the slit width is made sufficiently large, the wiring resistance may increase, which may degrade the display performance.

Abstract

The present invention provides a display, and a method of manufacturing the display. The display (1) comprises a first conductive layer (20) and a second conductive layer (21) formed relative to the first conductive layer (20) through an insulation layer (24). The display (1) is characterized in that it includes an overlapped part (40) where the first conductive layer (20) and the second conductive layer (21) are overlapped with each other, the overlapped part (40) includes a slit part (210a) formed in at least one of the first conductive layer (20) and the second conductive layer (21), and the width of the inner part (82) of the slit part (210a) excluding the both ends (81) is smaller than that of the both ends (81) of the slit part (210a).

Description

Technical field [0001] The present invention relates to a display device and a manufacturing method of the display device. Background technique [0002] Conventionally, there have been known display devices such as liquid crystal display devices, EL display devices, and plasma display devices in which pixel electrodes are arranged in a matrix on a transparent substrate and an image is formed by applying a voltage to each pixel electrode. As the driving method of these display devices, the active matrix driving method is a well-known technology. In the display device of the active matrix driving method, the gate bus lines (scanning wiring) and the source bus lines (signal wiring) are arranged in a grid pattern. On the transparent substrate, a switching element such as a TFT is provided near the intersection of the gate bus line and the source bus line. [0003] For example, on the TFT, a gate electrode branched from the gate bus line, a source electrode branched from the source bus...
