Since films must be deposited and these inorganic films must be accurately patterned, it is essential to reduce the coefficient of thermal expansion of the substrate.
  • composite plastic substrate By combining glass fillers and fibers with plastic, a substrate with a reduced coefficient of thermal expansion while maintaining transparency (hereinafter referred to as “composite plastic substrate”) has been developed.
  • Composite plastic substrates have properties that are intermediate between those of glass and plastic, and may be damaged in situations where local stresses are high. For example, this is the case where the corner of a hard object hits the substrate surface strongly. However, except under such severe conditions, it has been confirmed that the composite plastic substrate has high resistance to external forces and impacts, and is not damaged by external forces and impacts generated under normal use conditions of the display device. ing.

Or they propose a structure joined by double-sided tape. In this structure, since the reinforcing plate is provided on the entire surface including the display area of the liquid crystal panel, the light use efficiency is undesirably reduced. If the rigidity of the reinforcing plate is too high, the flexibility of the liquid crystal panel is impaired, and if the rigidity of the reinforcing plate is too low, the effect of suppressing breakage is reduced.

  • Glass substrates have a smaller breaking strain than plastic substrates and can be broken by relatively weak external force or impact. Can be effectively prevented. On the other hand, it is considered that it is difficult for a composite plastic substrate with relatively large breaking strain to absorb an external force or impact that generates enough distortion to cause the composite plastic substrate to be damaged by the elastic body.
