Active matrix, high definition, liquid crystal display structure
First Claim
1. Active matrix, liquid crystal screen structure having a first and a second transparent substrates (2, 4) spaced from one another and between which is interposed a liquid crystal film (6), the first substrate (2) essentially supporting colour filters (124) resistant to high temperatures and separated by black matrixes (126), a first transparent, passivating layer (128) deposited on the entire surface occupied by the filters and the black matrixes, thin film transistors (8, 9) formed on the first passivating layer facing the black matrixes so as to be protected from the ambient light, first, transparent, capacitor plates (10), formed on the first passivating layer facing the colour filters, each first plate being connected to a thin film transistor, electrode rows (14) and columns (12) for controlling said transistors and a second transparent, passivating layer (20) covering the transistors, the first plates, the rows and the columns, the second substrate (4) essentially having the second transparent capacitor plate (28), said second plates facing the first capacitor plates.

Abstract
This color display structure for color display purposes has a first and second spaced, transparent substrates, between which is interposed a liquid crystal film (6), the first substrate (2) essentially supporting color filters (124) resistant to high temperatures and separated by black matrixes (126), a first transparent, passivating layer (128) deposited on the entire surface occupied by the filters and the black matrixes, thin film transistors (8, 9), formed on the first passivating layer facing the black matrixes so as to be protected from the ambient light, first transparent capacitor plates (10) formed on the first passivating layer facing the color filters and connected to the transistors, electrode rows (14) and columns (12) for controlling these transistors and a second transparent passivating layer (20) covering the transistors, the first plates, the rows and the columns, the second substrate (4) essentially having the second transparent capacitor plate.
