Liquid crystal display device and manufacturing method thereof

A liquid crystal display device comprising:

• a TFT substrate, a counter substrate, a liquid crystal layer between the TFT substrate and the counter substrate,
• wherein a spacer is formed on the counter substrate to determine a distance between the TFT substrate and the counter substrate,
• a pixel electrode, a TFT (thin film transistor), and a plinth, which opposes to the spacer, are formed on the TFT substrate,
• a distance between the TFT substrate and a top of the plinth is bigger than a distance between the TFT substrate and a top of the pixel electrode,
• wherein an alignment film is formed on the plinth and between the pixel electrode and the liquid crystal layer,
• a first material and a second material are included in the alignment film,
• the first material exhibits more photo-alignment effect than the second material does,
• the alignment film is constituted by an upper layer and a lower layer, the upper layer is adjacent to the liquid crystal layer,
• a ratio in amount of the first material to the second material is bigger in the upper layer than in the lower layer,
• when the thickness of the lower layer of the alignment film is defined as p1 and the thickness of the upper layer of the alignment film is defined as p2, p2/p1 over the plinth is smaller than p2/p1 over the pixel electrode.
