習知技術中，液晶顯示模組通常包括一光源部和一液晶顯示面板。光線由光源部出射至液晶顯示面板。光源部和液晶顯示面板為兩個獨立的結構，並且光源部通常獨立電連接和承載於一個電路板上，因此，現有技術中的液晶顯示模組的厚度較大，不符合當前電子產品薄型化的要求。因此，如何減小液晶顯示模組的厚度是當前亟待解決的問題。
本發明目的在於提供一種厚度較小的液晶顯示模組。

本發明通過在薄膜電晶體陣列層的第一表面設置電路結構和第二表面設置薄膜電晶體，將電路結構和薄膜電晶體電連接，並將發光二極體晶片電連接於電路結構，使得液晶顯示模組的光源部和液晶顯示面板合成為一個整體，省去了現有技術中用於電連接和承載光源部的電路板，從而減小了液晶顯示模組的厚度。
