Display device

A display device comprising:

• a display panel, in which a display area and a non-display area are defined, wherein the display panel comprises:
• a plurality of first signal pads disposed in the non-display area, inclined at an inclination angle (θ) with respect to an imaginary center axis extending in a first direction, and disposed at one side of the imaginary center axis;
• a plurality of second signal pads disposed in the non-display area, inclined at the inclination angle (θ) with respect to the imaginary center axis, and disposed at the other side of the imaginary center axis;
• a first fixing pad;
• and
• a second fixing pad spaced apart from the first fixing pad with the first and second signal pads interposed therebetween;
• and a flexible film comprising:
• a plurality of first connection pads inclined at the inclination angle (θ) with respect to the imaginary center axis and disposed at one side of the imaginary center axis;
• a plurality of second connection pads inclined at the inclination angle (θ) with respect to the imaginary center axis and disposed at the other side of the imaginary center axis;
• a first alignment pad group;
• and
• a second alignment pad group spaced apart from the first alignment pad group with the first and second connection pads interposed therebetween,
• wherein
• the first alignment pad group comprises n first alignment pads which are sequentially arranged toward the display area and spaced apart from each other at a first distance and have a first length in the first direction,
• the second alignment pad group comprises n second alignment pads corresponding to the first alignment pads and having the first length in the first direction,
• a second distance between an m-th first alignment pad and an m-th second alignment pad and a third distance between an (m−1)-th first alignment pad and an (m−1)-th second alignment pad satisfy the following equation:
• tanθ=((d−c)/2)/(a+b), wherein a denotes the first distance, b denotes the first length, c denotes the second distance between the m-th first alignment pad and the m-th second alignment pad, and d denotes the third distance between the (m−1)-th first alignment pad and the (m−1)-th second alignment pad, and
• n is an integer equal to or greater than 3, and m is an integer equal to or greater than 2 and equal to or less than n.
