Display device such as electro-optic element and thin film transistor and display device manufacturing method

A display device manufacturing method for forming an opening region including an electro-optic element for emitting light through a transparent base plate and a non-opening region including a thin film transistor for driving said electro-optic element in each pixel disposed in a matrix on said base plate, said method comprising the steps of:

• forming a first film body including said thin film transistor in said non-opening region, and
• forming a second film body extending from said first film body and existing between said electro-optic element and said base plate, wherein:
• said second film body varies from said first film body so as to adjust the light passing through said opening region,
• whereby said second film structure varies from said first film structure such that said a refractive index of said second film structure is closer to a refractive index of said base plate than that of said first film structure.

A liquid crystal display device including pixels disposed in a matrix on a transparent base plate, each pixel having an opening region, in which an electro-optic element for emitting light through said base plate is formed, and a non-opening region, in which a thin film transistor for driving said electro-optic element is formed, said electro-optic element being made by holding a liquid crystal material between transparent electrodes opposing to each other, said electro-optic element emitting light that has entered from one surface side of the base plate to another surface side of the base plate, wherein:

• said non-opening region has a first film structure including said thin film transistor,
• said opening region has a second film structure extending from said first film structure and existing between said electro-optic element and said base plate, and
• said second film structure varies from said first film structure so as to adjust the light passing through said opening region,
• wherein said second film structure varies from said first film structure such that said a refractive index of said second film structure is closer to a refractive index of said base plate than that of said first film structure.
