1. A method for inspecting image data of a display device including a data processing device and a data driving device, the method comprising:
generating, by the data processing device, first cyclic redundancy check (CRC) data for partial areas among areas of image data of a first frame and transmitting the image data of the first frame and the first CRC data to the data driving device;
receiving, by the data driving device, the image data of the first frame and the first CRC data and generating second CRC data for the partial areas among areas of the image data of the first frame on the basis of the image data of the first frame; and
comparing, by the data driving device, the first CRC data with the second CRC data to determine whether there is an error in the partial areas among areas of the image data of the first frame, wherein
the first frame includes the image data and first horizontal line data associated with a horizontal line,
the first horizontal line data includes the first CRC data,
the first horizontal line data comprises a first portion and a second portion,
the first portion includes CRC data,
the second portion includes dummy data,
CRC data for all sub-pixels included in one area of the partial areas is sequentially included in the first horizontal line data, and
CRC data for all sub-pixels included in another area of the partial areas is sequentially included in the first horizontal line data.
