LIQUID CRYSTAL DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18517038 titled 'LIQUID CRYSTAL DISPLAY DEVICE
Simplified Explanation
The liquid crystal display device described in the patent application includes a TFT substrate and a counter substrate with a liquid crystal layer in between. The TFT substrate has an organic passivation film, a pixel electrode, and a common electrode. A columnar spacer is formed on the counter substrate to define a distance between the two substrates. A planarization film made of resin is formed in a through-hole in the organic passivation film, creating a recess where the tip end of the columnar spacer is located.
- TFT substrate with organic passivation film, pixel electrode, and common electrode
- Columnar spacer on counter substrate to define distance
- Planarization film in through-hole creating recess for columnar spacer

Original Abstract Submitted
A liquid crystal display device includes a thin film transistor (TFT) substrate and a counter substrate that are disposed opposite to each other with a liquid crystal layer in between. The TFT substrate has, an organic passivation film formed covering the TFT, and a pixel electrode and a common electrode formed on the organic passivation film, the organic passivation film having a through-hole to connect the pixel electrode and the TFT. A columnar spacer is formed on the counter substrate to define a distance between the TFT substrate and the counter substrate. A planarization film made of resin is formed in the through-hole. A recess is formed in the through-hole by a surface of the planarization film and a sidewall of the through-hole. A tip end of the columnar spacer exists in the recess.
