1. A display device comprising:

  • a base substrate including a plurality of pixel areas at which an image is displayed;

    a light blocking pattern on the base substrate;

    a thin film transistor on the light blocking pattern;

    a pixel electrode in each of the pixel areas, a dimension of the pixel electrode in a first direction being larger than a dimension of the pixel electrode in a second direction crossing the first direction; and

    a gate line and a data line each connected to the thin film transistor,whereinone line among the gate line and the data line has a length extending along the larger dimension of the pixel electrode,the other line among the gate line and the data line has a length extending along the smaller dimension of the pixel electrode,in the second direction;

    a first pixel electrode is adjacent to and spaced apart from a second pixel electrode, andthe one line having the length extending along the larger dimension of the pixel electrode is spaced apart from the first pixel electrode and overlaps the second pixel electrode, andthe light blocking pattern comprises;

    a first light blocking pattern defining a length thereof extending along the larger dimension of the pixel electrode,along the second direction, the first light blocking pattern spaced apart from the second pixel electrode and overlapping the pixel electrode and the one line having the length extending along the larger dimension of the pixel electrode; and

    a second light blocking pattern of which a portion thereof overlaps the thin film transistor, the second light blocking pattern having first and second edges extending along the second direction between the pixel electrode and the other line having the length extending along the smaller dimension of the pixel electrode,whereinthe first edge of the second light blocking pattern is adjacent to and spaced apart from the other line having the length extending along the smaller dimension of the pixel electrode,the second edge of the second light blocking pattern is adjacent to and spaced apart from the pixel electrode, andthe thin film transistor is disposed between the first and second edges of the second light blocking pattern.
