A TEG (Test Element Group) block 1 includes a TFT (Thin Film Transistor) test element and a capacitance test element that are arranged adjacent to each other, and six test terminals. A TEG block 2 includes a resistance test element and a capacitance test element that are arranged adjacent to each other, and six test terminals. In these TEG blocks, the test terminals are arranged with the same pattern. Each of the test elements in each TEG block is connected to at least one of a plurality of test terminals included in that TEG block. The test elements can be efficiently formed on the substrate in view of the space on a display device substrate or the preference of characteristics to be evaluated. Moreover, characteristics of each test element can be conducted with a common probe regardless of the type of display device.
