The present thesis, Brazilian Soap Operas: The construction of transgender characters on Globo TV, presents a deep discussion about who are the transgender characters on the soap operas, as well as how these characters were built. The research offers an unprecedented survey on LGBTs characters existing in the Globo TV soap operas since 1965 – inauguration of the company – until the year 2017, where it was possible to map the transsexual characters, focus of this work. In this way, to understand the construction of transgender characters, 16 professionals of the company were listened to - among actors, authors, directors and managers - who were directly linked to the creation of the three transsexual characters existing in the dramaturgy of Globo TV in the specified period: Ramona, a trans woman, in the soap opera As Filhas da Mãe, in 2001, Dorothy, trans woman, in the soap opera Geração Brasil, in 2014 and Ivan, man trans, in the soap opera A Força do Querer, de 2017. We can identify the resources used by the professionals involved in the construction of the identity and messages delivered by each of the characters studied along the respective plots. In order to analyze the way in which trans characters were constructed, bibliographical references on gender and the theme of contemporary transgenerity were used, as well as research on the importance of television and telenovelas in social debates in Brazil. Finally, this study exposes – in an unprecedented way – reflections on the subject directions within the dramaturgy, what could have been done and was not and the ways for the discussion of this theme to be treated, increasingly, with responsibility and relevance in Brazilian soap operas.
