Embodiment Construction

[0049] An active matrix substrate according to an embodiment of the present invention includes: a plurality of scanning wirings formed in parallel with each other in a display area; and a plurality of scanning wirings formed in parallel with each other in the display area. Data wiring; and multiple scan terminals and multiple data terminals arranged in the terminal configuration area. The plurality of scanning wirings described above includes: a plurality of first scanning wirings having an input terminal of a scanning signal on one end side; and a plurality of second scanning wirings having an input terminal of a scanning signal on the other end side. In the display area, the first scan wiring and the second scan wiring are alternately formed each. The active matrix substrate includes: a plurality of first connection wirings connecting the scanning signal input ends of the first scanning wiring and the scanning terminal; and connecting the scanning signal input ends of the sec...

Abstract

Provided is an active matrix substrate having improved display qualities without forming an inspection wiring in a terminal arrangement region for inspecting a short-circuit between connecting wirings. A scanning wiring (40) includes a first scanning wiring having an input end for a scanning signal on one end side, and a second scanning wiring having an input end for a scanning signal on the other end side. In a display region (4), the first scanning wirings and the second scanning wirings are alternately formed one by one. An active matrix substrate (2) is provided with a first inspection wiring (70) and a second inspection wiring (72) which intersect with first connecting wirings (61), and a third inspection wiring (75) and a fourth inspection wiring (77) which intersect with second connecting wirings (64). The first to the fourth inspection wirings (70, 72, 75, 77) are formed in a frame wiring region (6), excluding a terminal arrangement region (5) and the display region (4).

Description

Technical field [0001] The present invention relates to an active matrix substrate, a display device, an inspection method of the active matrix substrate, and an inspection method of the display device. The active matrix substrate has a display area in which a plurality of input terminals for scanning signals are provided on one end side. One first scanning wiring and a plurality of second scanning wirings having scanning signal input terminals on the other end side are formed alternately and parallel to each other, and the plurality of data wirings are connected to the plurality of first scanning wirings. It is formed so as to cross the plurality of second scanning lines and to be parallel to each other. Background technique [0002] In recent years, liquid crystal panels have been widely used in various electronic devices such as mobile phones, PDAs, car navigation systems, personal computers, televisions, video cameras, and digital cameras. The liquid crystal panel has the ad...
