Display module

A display module comprising:

• a substrate;
• a driving circuit layer formed on the substrate, the driving circuit layer comprising first driving circuits and second driving circuits;
• and
• a pixel array, comprising a plurality of pixels, formed on the driving circuit layer, each pixel including a plurality of inorganic light-emitting devices, the plurality of pixels being arranged in a matrix form,
• wherein a first driving circuit from among the first driving circuits is provided for each pixel, and the first driving circuits drive the plurality of inorganic light-emitting devices included in each pixel based on data voltages applied through data lines,
• wherein the second driving circuits generate control signals for driving the first driving circuits based on clock signals applied through clock lines, and provide the generated control signals to the first driving circuits,
• wherein the first driving circuits and the second driving circuits comprise a plurality of thin film transistors (TFTs), and
• wherein the driving circuit layer comprises:
• a first metal layer at which gate electrodes of the plurality of TFTs are formed;
• a second metal layer at which source electrodes and drain electrodes of the plurality of TFTs, the clock lines, and the data lines are formed;
• an inter-layer dielectric formed between the first metal layer and the second metal layer;
• and
• at least one third metal layer at which electrodes that provide a voltage for driving the first driving circuits are formed,
• wherein the clock signals are applied from the clock lines to the second driving circuits through jumping lines formed in the at least one third metal layer,
• wherein the voltage for driving the first driving circuits is a driving voltage or a ground voltage, and
• wherein the clock lines are arranged in a column direction, and the first driving circuits are between the clock lines and the second driving circuits in a horizontal direction.
