Each of the signal conversion lines of the array substrate extends in the first direction, and connects two connection terminals adjacent to the each of signal conversion lines. Projections of the connection terminals on the reference plane in the second direction do not overlap. In this manner, the design that the adjacent connection terminals are interlaced can increase the spacing between the adjacent connection terminals, thus resolving the problem that the spacing between connection terminals on the array substrate is excessively small and short circuiting tends to happen when bonding to cause poor bonding in the related art.
